Given numbers are 636, 328, 644, 681

The list of prime factors of all numbers are

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 328 are 2 x 2 x 2 x 41

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 681 are 3 x 227

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

Given numbers are 636, 328, 644, 681

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

Apply this formula for all numbers.

Step1:

LCM(636, 328) = 52152

GCD(636, 328) = ( 636 x 328 ) / 52152

= 636 / 328

= 636

Step2:

LCM(4, 644) = 644

GCD(4, 644) = ( 4 x 644 ) / 644

= 4 / 644

= 4

Step3:

LCM(4, 681) = 2724

GCD(4, 681) = ( 4 x 681 ) / 2724

= 4 / 681

= 4

So, Greatest Common Divisor of 636, 328, 644, 681 is 1
