Given numbers are 640, 904, 957, 416

The list of prime factors of all numbers are

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

Prime factors of 904 are 2 x 2 x 2 x 113

Prime factors of 957 are 3 x 11 x 29

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

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

Given numbers are 640, 904, 957, 416

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

Apply this formula for all numbers.

Step1:

LCM(640, 904) = 72320

GCD(640, 904) = ( 640 x 904 ) / 72320

= 640 / 904

= 640

Step2:

LCM(8, 957) = 7656

GCD(8, 957) = ( 8 x 957 ) / 7656

= 8 / 957

= 8

Step3:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

So, Greatest Common Divisor of 640, 904, 957, 416 is 1
