Given numbers are 686, 718, 317, 156

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

Apply this formula for all numbers.

Step1:

LCM(686, 718) = 246274

GCD(686, 718) = ( 686 x 718 ) / 246274

= 686 / 718

= 686

Step2:

LCM(2, 317) = 634

GCD(2, 317) = ( 2 x 317 ) / 634

= 2 / 317

= 2

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 686, 718, 317, 156 is 1
