GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 979) = 642224
GCD(656, 979) = ( 656 x 979 ) / 642224
= 656 / 979
= 656
Step2:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 656, 979, 634, 940 is 1
