Given numbers are 656, 418, 193, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 418) = 137104
GCD(656, 418) = ( 656 x 418 ) / 137104
= 656 / 418
= 656
Step2:
LCM(2, 193) = 386
GCD(2, 193) = ( 2 x 193 ) / 386
= 2 / 193
= 2
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 656, 418, 193, 820 is 1
