How do you explain GCF?

When we find all the factors of two or more numbers, and some factors are the same (“common”), then the largest of those common factors is the Greatest Common Factor. Example: the GCF of 12 and 16 is 4, because 1, 2 and 4 are common factors of both 12 and 16, and 4 is the greatest of them.

What is the GCF of 4 and 6?

What is the Greatest Common Factor of 4 and 6? Greatest common factor (GCF) of 4 and 6 is 2. We will now calculate the prime factors of 4 and 6, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 6.

What is the GCF of 12?

Finding the Greatest Common Factor

Two Numbers Factors Greatest Common Factor
9 and 12 9: 1, 3, 9 12: 1, 2, 3, 4, 6, 12 3

What is the GCF of 24 36 and 72?

Step-by-step explanation: Looking at these three numbers, we see that the biggest number they share is of the form: , where is just 12.

What is the GCF of 15 and 32?

What is the Greatest Common Factor of 15 and 32? Greatest common factor (GCF) of 15 and 32 is 1.

What is the GCF of 54 and 64?

What is the Greatest Common Factor of 54 and 64? Greatest common factor (GCF) of 54 and 64 is 2.

What is the LCM of 6 and 18?

Answer: LCM of 6 and 18 is 18.

What is the lowest common multiple of 10 12 and 15?

The LCM of 10,12,15 10 , 12 , 15 is the result of multiplying all prime factors the greatest number of times they occur in either number. The LCM of 10,12,15 10 , 12 , 15 is 2⋅2⋅3⋅5=60 2 ⋅ 2 ⋅ 3 ⋅ 5 = 60 .

What is the GCF of 24 and 40?

The GCF of 24 and 40 is 8. A factor of the number a is any whole number that divides into a evenly. The greatest common factor of two numbers, a and…

What is the GCF of three numbers?

In other words, the GCF of 3 or more numbers can be found by finding the GCF of 2 numbers and using the result along with the next number to find the GCF and so on. So, the greatest common factor of 120 and 50 is 10. So, the greatest common factor of 20 and 10 is 10.

What is the LCM of 10 15 and 20?

Therefore, the LCM of 10, 15 and 20 is 60. If we have 3 numbers, we use a division method to find the LCM. Suppose if we want to find LCM of 2 numbers, we use the formula and hence we obtain the solution. So, the correct answer is “60”.

What is the LCM of 10 15 and 30?

Least Common Multiple of 10 and 15. Free LCM Calculator determines the least common multiple (LCM) between 10 and 15 the smallest integer that is 30 that is divisible by both numbers. Least Common Multiple (LCM) of 10 and 15 is 30.

What is the LCM of 10 15 and 25?

150

What is the GCF of 16 and 24?

We found the factors and prime factorization of 16 and 24. The biggest common factor number is the GCF number. So the greatest common factor 16 and 24 is 8.

What is the HCF of 16 20 and 24?

So the greatest common factor 16,20,24,32 is 4.

What is the GCF of 28 and 36?

4

What is the GCF of 16 and 30?

We found the factors and prime factorization of 16 and 30. The biggest common factor number is the GCF number. So the greatest common factor 16 and 30 is 2.

How do you explain GCF?

The greatest common factor (GCF) is a term used to describe the biggest number that can divide evenly into two or more numbers. Sometimes, this is also referred to as the greatest common divisor (GCD) or highest common factor (HCF). A factor is a smaller number that can divide evenly into that number.

What is the GCF of 2 and 4?

GCF of 2 and 4 by Listing Common Factors There are 2 common factors of 2 and 4, that are 1 and 2. Therefore, the greatest common factor of 2 and 4 is 2.

What is the GCF for 8 and 12?

4
Answer: GCF of 8 and 12 is 4.

What is the GCF of 4 and 6?

2
Answer: GCF of 4 and 6 is 2.

When would you use greatest common factor in real life?

We use greatest common factors all the time with fractions, and as fractions are used a lot in everyday life, this makes GCF very useful! By finding the GCF of the denominator and numerator, you can then successfully simplify a fraction or ratio. E.g. We can simplify 3045 by knowing that its HCF is 15 .

What is the highest common factor of 3 and 5?

1
Answer: GCF of 3 and 5 is 1.

What is the greatest common factor of 24 and 36?

12
GCF of 24 and 36 by Listing Common Factors Therefore, the greatest common factor of 24 and 36 is 12.

How do you find the common factors?

To find the common factors of two numbers, you first need to list all the factors of each one and then compare them. If a factor appears in both lists then it is a common factor.

What is the greatest common factor 8 and 10?

Answer: GCF of 8 and 10 is 2.

How do you calculate the highest common factor?

To find the greatest common factor (GCF) between numbers, take each number and write it’s prime factorization. Then, identify the factors common to each number and multiply those common factors together.

What is the greatest common factor of 12 and 20?

The gcf of 12 and 20 can be obtained like this: The factors of 12 are 12, 6, 4, 3, 2, 1. The factors of 20 are 20, 10, 5, 4, 2, 1. The common factors of 12 and 20 are 4, 2, 1, intersecting the two sets above. In the intersection factors of 12 ∩ factors of 20 the greatest element is 4. Therefore, the greatest common factor of 12 and 20 is 4.

What is an example of greatest common factor?

The greatest common factor (GCF) of a set of numbers is the largest number that is a factor of all those numbers. For example, the GCF of the numbers 4 and 6 is 2 because 2 is the greatest number that’s a factor of both 4 and 6.

What is the GCF of 4 and 7?

The GCF of 4 and 7 is 1. The factors of 4 are 1, 2, and 4. The factors of 7 are 1 and 7. 1 is the greatest number that they have in common so 1 is the GCF.
