Given numbers are 691, 570, 596, 657

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

Apply this formula for all numbers.

Step1:

LCM(691, 570) = 393870

GCD(691, 570) = ( 691 x 570 ) / 393870

= 691 / 570

= 691

Step2:

LCM(1, 596) = 596

GCD(1, 596) = ( 1 x 596 ) / 596

= 1 / 596

= 1

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 691, 570, 596, 657 is 1
