Given numbers are 640, 638, 437, 908

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 638 are 2 x 11 x 29

Prime factors of 437 are 19 x 23

Prime factors of 908 are 2 x 2 x 227

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

Given numbers are 640, 638, 437, 908

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

Apply this formula for all numbers.

Step1:

LCM(640, 638) = 204160

GCD(640, 638) = ( 640 x 638 ) / 204160

= 640 / 638

= 640

Step2:

LCM(2, 437) = 874

GCD(2, 437) = ( 2 x 437 ) / 874

= 2 / 437

= 2

Step3:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

So, Greatest Common Divisor of 640, 638, 437, 908 is 1
