Given numbers are 684, 288, 491, 129

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 491 are 491

Prime factors of 129 are 3 x 43

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

Given numbers are 684, 288, 491, 129

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

Apply this formula for all numbers.

Step1:

LCM(684, 288) = 5472

GCD(684, 288) = ( 684 x 288 ) / 5472

= 684 / 288

= 684

Step2:

LCM(36, 491) = 17676

GCD(36, 491) = ( 36 x 491 ) / 17676

= 36 / 491

= 36

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 684, 288, 491, 129 is 1
