Detailed Solution to Calculate GCF of 280, 285 using Factoring

In this method, we have to list the factors of 280 and 285 separately and then select the highest number that appears in both lists. This will be your greatest common factor.

The factors of 280 are 1 , 2 , 4 , 5 , 7 , 8 , 10 , 14 , 20 , 28 , 35 , 40 , 56 , 70 , 140 , and 280

The factors of 285 are 1 , 3 , 5 , 15 , 19 , 57 , 95 , and 285

As you can see from the aforementioned lists, the largest number that is present in both lists is 5. Therefore, we can determine that the GCF of 280 and 285 is 5.

Greatest Common Factor of 280, 285 with Prime Factorization

This is prime factorization. Essentially, you have to divide both 280 and 285 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.

5	280, 285
	56, 57

From the picture, we can see that 56 and 57 cannot be divided by the same number again. So, all we have to do is now multiply the prime numbers on the left.

5 = 5

Hence, the GCF of 280 and 285 is 5.
