Given numbers are 656, 220, 921, 460
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 220) = 36080
GCD(656, 220) = ( 656 x 220 ) / 36080
= 656 / 220
= 656
Step2:
LCM(4, 921) = 3684
GCD(4, 921) = ( 4 x 921 ) / 3684
= 4 / 921
= 4
Step3:
LCM(1, 460) = 460
GCD(1, 460) = ( 1 x 460 ) / 460
= 1 / 460
= 1
So, Greatest Common Divisor of 656, 220, 921, 460 is 1
