GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 891) = 584496
GCD(656, 891) = ( 656 x 891 ) / 584496
= 656 / 891
= 656
Step2:
LCM(1, 334) = 334
GCD(1, 334) = ( 1 x 334 ) / 334
= 1 / 334
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 656, 891, 334, 221 is 1
