GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(268, 640) = 42880
GCD(268, 640) = ( 268 x 640 ) / 42880
= 268 / 640
= 268
Step2:
LCM(4, 454) = 908
GCD(4, 454) = ( 4 x 454 ) / 908
= 4 / 454
= 4
Step3:
LCM(2, 916) = 916
GCD(2, 916) = ( 2 x 916 ) / 916
= 2 / 916
= 2
So, Greatest Common Divisor of 268, 640, 454, 916 is 2
