What is GCF?
Greatest Common Factor (GCF), also known as the Greatest Common Divisor (GCD), is the largest positive integer that divides each of the numbers without a remainder.
How to Find GCF:
- Prime Factorization Method: Break each number into prime factors and multiply the common ones
- Euclidean Algorithm: Repeatedly divide and use remainders until reaching zero
- Listing Factors: List all factors of each number and find the greatest common one
