Detailed Solution to Calculate GCF of 36, 42 using Factoring

In this method, we have to list the factors of 36 and 42 separately and then select the highest number that appears in both lists. This will be your greatest common factor.

The factors of 36 are 1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , and 36

The factors of 42 are 1 , 2 , 3 , 6 , 7 , 14 , 21 , and 42


As you can see from the aforementioned lists, the largest number that is present in both lists is 6. Therefore, we can determine that the GCF of 36 and 42 is 6.


Greatest Common Factor of 36, 42 with Prime Factorization

This is prime factorization. Essentially, you have to divide both 36 and 42 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  36,   42
3  18,   21
 6,   7

From the picture, we can see that 6 and 7 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 36 and 42 is 6.
