Steps to Calculate GCD of 491, 556, 69, 222 using LCM Formula
Given numbers are 491, 556, 69, 222
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 556) = 272996
GCD(491, 556) = ( 491 x 556 ) / 272996
= 491 / 556
= 491
Step2:
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
= 1 / 69
= 1
Step3:
LCM(1, 222) = 222
GCD(1, 222) = ( 1 x 222 ) / 222
= 1 / 222
= 1
So, Greatest Common Divisor of 491, 556, 69, 222 is 1
