What is the Greatest common Divisor of 100 and 980?

Answer: GCF of 100 and 980 is 20

(Twenty)

Finding GCF for 100 and 980 using all factors (divisors) listing

The first method to find GCF for numbers 100 and 980 is to list all factors for both numbers and pick the highest common one:

All factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100

All factors of 980: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

So the Greatest Common Factor for 100 and 980 is 20

Finding GCF for 100 and 980 by Prime Factorization

The second method to find GCF for numbers 100 and 980 is to list all Prime Factors for both numbers and multiply the common ones:

All Prime Factors of 100: 2, 2, 5, 5

All Prime Factors of 980: 2, 2, 5, 7, 7

As we can see there are Prime Factors common to both numbers: 2, 2, 5

Now we need to multiply them to find GCF: 2 × 2 × 5 = 20
