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.

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.

What is the highest common factor?

The Highest Common Factor (H.C.F) of two (or more) numbers is the largest number that divides evenly into both numbers. In other words the H.C.F is the largest of all the common factors. The common factors or of 12 and 18 are 1, 2, 3 and 6.
