Given numbers are 687, 258, 928, 108

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 258 are 2 x 3 x 43

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

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 687, 258, 928, 108

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

Apply this formula for all numbers.

Step1:

LCM(687, 258) = 59082

GCD(687, 258) = ( 687 x 258 ) / 59082

= 687 / 258

= 687

Step2:

LCM(3, 928) = 2784

GCD(3, 928) = ( 3 x 928 ) / 2784

= 3 / 928

= 3

Step3:

LCM(1, 108) = 108

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

= 1 / 108

= 1

So, Greatest Common Divisor of 687, 258, 928, 108 is 1
