Given numbers are 684, 686, 813, 137

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 686 are 2 x 7 x 7 x 7

Prime factors of 813 are 3 x 271

Prime factors of 137 are 137

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

Given numbers are 684, 686, 813, 137

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

Apply this formula for all numbers.

Step1:

LCM(684, 686) = 234612

GCD(684, 686) = ( 684 x 686 ) / 234612

= 684 / 686

= 684

Step2:

LCM(2, 813) = 1626

GCD(2, 813) = ( 2 x 813 ) / 1626

= 2 / 813

= 2

Step3:

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

= 1 / 137

= 1

So, Greatest Common Divisor of 684, 686, 813, 137 is 1
