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
