Given numbers are 640, 645, 732, 418

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 645 are 3 x 5 x 43

Prime factors of 732 are 2 x 2 x 3 x 61

Prime factors of 418 are 2 x 11 x 19

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

Given numbers are 640, 645, 732, 418

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

Apply this formula for all numbers.

Step1:

LCM(640, 645) = 82560

GCD(640, 645) = ( 640 x 645 ) / 82560

= 640 / 645

= 640

Step2:

LCM(5, 732) = 3660

GCD(5, 732) = ( 5 x 732 ) / 3660

= 5 / 732

= 5

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 640, 645, 732, 418 is 1
