Given numbers are 645, 317, 672, 902

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 317 are 317

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 902 are 2 x 11 x 41

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

Given numbers are 645, 317, 672, 902

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

Apply this formula for all numbers.

Step1:

LCM(645, 317) = 204465

GCD(645, 317) = ( 645 x 317 ) / 204465

= 645 / 317

= 645

Step2:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

Step3:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

So, Greatest Common Divisor of 645, 317, 672, 902 is 1
