GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 764) = 125296
GCD(656, 764) = ( 656 x 764 ) / 125296
= 656 / 764
= 656
Step2:
LCM(4, 948) = 948
GCD(4, 948) = ( 4 x 948 ) / 948
= 4 / 948
= 4
Step3:
LCM(4, 391) = 1564
GCD(4, 391) = ( 4 x 391 ) / 1564
= 4 / 391
= 4
So, Greatest Common Divisor of 656, 764, 948, 391 is 1
