Steps to Calculate GCD of 406, 221, 42, 501 using LCM Formula
Given numbers are 406, 221, 42, 501
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 221) = 89726
GCD(406, 221) = ( 406 x 221 ) / 89726
= 406 / 221
= 406
Step2:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
Step3:
LCM(1, 501) = 501
GCD(1, 501) = ( 1 x 501 ) / 501
= 1 / 501
= 1
So, Greatest Common Divisor of 406, 221, 42, 501 is 1
