6 Answer: GCF of 12 and 30 is 6.
How do you calculate GCF?
Here’s how to find the GCF of a set of numbers using prime factorization:
- List the prime factors of each number.
- Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
- Multiply all the circled numbers. The result is the GCF.
