What does common prime factors mean?
When two or more numbers have one or more of the same primes as factors, those prime factors are called common prime factors. For example, the prime factors of 6 are 2 and 3, and the prime factors of 21 are 3 and 7, so 3 is a common prime factor of 6 and 21.
What is the greatest common factor for 21 and 36?
The factors of 21 are 1, 3, 7, and 21. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors they have in common are 1 and 3, the largest of which is 3, so 3 is the greatest common factor. Or, you can calculate the greatest common factor by looking at the prime factors. The prime factors of 21 are 3 and 7. The prime factors of 36 are 2, 2, 3, and 3. The prime factors they have in common are a single 3, so 3 is the greatest common factor.
