Greatest Common Factor of 390, 396 with Prime Factorization

This is prime factorization. Essentially, you have to divide both 390 and 396 with the same prime number and keep going until the numbers can no longer be divided by the same prime number. At that point, you must stop the process and multiply the prime numbers on the left side. The result will be the greatest common factor.

2  390,   396
3  195,   198
 65,   66

From the picture, we can see that 65 and 66 cannot be divided by the same number again. So, all we have to do is now multiply the prime numbers on the left.

2 x 3 = 6

Hence, the GCF of 390 and 396 is 6.
