Given numbers are 857, 819, 636, 108

The list of prime factors of all numbers are

Prime factors of 857 are 857

Prime factors of 819 are 3 x 3 x 7 x 13

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

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

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

Given numbers are 857, 819, 636, 108

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

Apply this formula for all numbers.

Step1:

LCM(857, 819) = 701883

GCD(857, 819) = ( 857 x 819 ) / 701883

= 857 / 819

= 857

Step2:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

Step3:

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

= 1 / 108

= 1

So, Greatest Common Divisor of 857, 819, 636, 108 is 1
