Given numbers are 129, 591, 239, 656
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 591) = 25413
GCD(129, 591) = ( 129 x 591 ) / 25413
= 129 / 591
= 129
Step2:
LCM(3, 239) = 717
GCD(3, 239) = ( 3 x 239 ) / 717
= 3 / 239
= 3
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 129, 591, 239, 656 is 1
