Steps to Calculate GCD of 556, 454, 91, 140 using LCM Formula
Given numbers are 556, 454, 91, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 454) = 126212
GCD(556, 454) = ( 556 x 454 ) / 126212
= 556 / 454
= 556
Step2:
LCM(2, 91) = 182
GCD(2, 91) = ( 2 x 91 ) / 182
= 2 / 91
= 2
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 556, 454, 91, 140 is 1
