Given numbers are 664, 640, 961, 128

The list of prime factors of all numbers are

Prime factors of 664 are 2 x 2 x 2 x 83

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

Prime factors of 961 are 31 x 31

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 664, 640, 961, 128

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

Apply this formula for all numbers.

Step1:

LCM(664, 640) = 53120

GCD(664, 640) = ( 664 x 640 ) / 53120

= 664 / 640

= 664

Step2:

LCM(8, 961) = 7688

GCD(8, 961) = ( 8 x 961 ) / 7688

= 8 / 961

= 8

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 664, 640, 961, 128 is 1
