Given numbers are 957, 943, 640, 655

The list of prime factors of all numbers are

Prime factors of 957 are 3 x 11 x 29

Prime factors of 943 are 23 x 41

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

Prime factors of 655 are 5 x 131

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

Given numbers are 957, 943, 640, 655

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

Apply this formula for all numbers.

Step1:

LCM(957, 943) = 902451

GCD(957, 943) = ( 957 x 943 ) / 902451

= 957 / 943

= 957

Step2:

LCM(1, 640) = 640

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

= 1 / 640

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 957, 943, 640, 655 is 1
