Why 69 is not a prime number?

For 69 to be a prime number, it would have been required that 69 has only two divisors, i.e., itself and 1. However, 69 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 69 = 3 x 23, where 3 and 23 are both prime numbers.

How do you factor out the GCF?

Factoring out the GCF is the first step in many factoring problems. Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common. Step 2: Factor out (or divide out) the greatest common factor from each term.

How do you calculate the greatest 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.

How do you factor out a common factor?

Example: Follow these steps to factor out the expression Determine a common factor. A common factor is 2. Divide each term by the common factor and write the results of the division in parentheses, with the factor out in front. Determine whether you can factor out any other terms. The terms left in the parentheses are still too large.

How do you find the GCF of a fraction?

Find the greatest common factor (GCF) of the numerator and denominator. Divide the top and bottom numbers of the fraction by the GCF to reduce to the lowest term. You can find the GCF either by trial and error when the numbers are relatively small, or using Prime Factorization.
