Given numbers are 656, 657, 30

The list of prime factors of all numbers are

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 657 are 3 x 3 x 73

Prime factors of 30 are 2 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 656, 657, 30

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(656, 657) = 430992

GCD(656, 657) = ( 656 x 657 ) / 430992

= 656 / 657

= 656

Step2:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

So, Greatest Common Divisor of 656, 657, 30 is 1
