The list of prime factors of all numbers are

Prime factors of 977 are 977

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 847 are 7 x 11 x 11

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 977, 756, 847, 640

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

Apply this formula for all numbers.

Step1:

LCM(977, 756) = 738612

GCD(977, 756) = ( 977 x 756 ) / 738612

= 977 / 756

= 977

Step2:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 977, 756, 847, 640 is 1
