Given numbers are 971, 570, 129, 656

The list of prime factors of all numbers are

Prime factors of 971 are 971

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 129 are 3 x 43

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

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

Given numbers are 971, 570, 129, 656

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

Apply this formula for all numbers.

Step1:

LCM(971, 570) = 553470

GCD(971, 570) = ( 971 x 570 ) / 553470

= 971 / 570

= 971

Step2:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 971, 570, 129, 656 is 1
