How do you find the LCM of 28 and 42?
How do you do the GCF step by step?
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.
