Given numbers are 657, 646, 317

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

Apply this formula for all numbers.

Step1:

LCM(657, 646) = 424422

GCD(657, 646) = ( 657 x 646 ) / 424422

= 657 / 646

= 657

Step2:

LCM(1, 317) = 317

GCD(1, 317) = ( 1 x 317 ) / 317

= 1 / 317

= 1

So, Greatest Common Divisor of 657, 646, 317 is 1
