What are facts for GCF?

Answer 1

The facts of GCF are that:

• The GCF divides the terms given. For instance, we have 4 and 2. The GCF is 2, so 4 / 2 = 2 and 2 / 2 = 1!
• Perform the prime factorization of the terms and check for the common factors for these terms.
• If no non-one common factors appear in all factors of the terms, then the GCF is 1. For instance, the gcf of 3 and 4 is 1.
• Otherwise, the GCF is not 1.
• The GCF of any primes is 1.

Answer 2

Example: 30 and 42

Factor them.

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Select the common factors.

2 x 3 = 6, the GCF
