Given numbers are 636, 371, 646, 855

The list of prime factors of all numbers are

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

Prime factors of 371 are 7 x 53

Prime factors of 646 are 2 x 17 x 19

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 636, 371, 646, 855

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

Apply this formula for all numbers.

Step1:

LCM(636, 371) = 4452

GCD(636, 371) = ( 636 x 371 ) / 4452

= 636 / 371

= 636

Step2:

LCM(53, 646) = 34238

GCD(53, 646) = ( 53 x 646 ) / 34238

= 53 / 646

= 53

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 636, 371, 646, 855 is 1
