GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 987) = 647472
GCD(656, 987) = ( 656 x 987 ) / 647472
= 656 / 987
= 656
Step2:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
Step3:
LCM(1, 968) = 968
GCD(1, 968) = ( 1 x 968 ) / 968
= 1 / 968
= 1
So, Greatest Common Divisor of 656, 987, 763, 968 is 1
