Given numbers are 686, 137, 840, 271

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 137 are 137

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 271 are 271

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

Given numbers are 686, 137, 840, 271

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

Apply this formula for all numbers.

Step1:

LCM(686, 137) = 93982

GCD(686, 137) = ( 686 x 137 ) / 93982

= 686 / 137

= 686

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 271) = 271

GCD(1, 271) = ( 1 x 271 ) / 271

= 1 / 271

= 1

So, Greatest Common Divisor of 686, 137, 840, 271 is 1
