Given numbers are 656, 645, 124, 884

The list of prime factors of all numbers are

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 645 are 3 x 5 x 43

Prime factors of 124 are 2 x 2 x 31

Prime factors of 884 are 2 x 2 x 13 x 17

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

Given numbers are 656, 645, 124, 884

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

Apply this formula for all numbers.

Step1:

LCM(656, 645) = 423120

GCD(656, 645) = ( 656 x 645 ) / 423120

= 656 / 645

= 656

Step2:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

Step3:

LCM(1, 884) = 884

GCD(1, 884) = ( 1 x 884 ) / 884

= 1 / 884

= 1

So, Greatest Common Divisor of 656, 645, 124, 884 is 1
