Steps to Calculate GCD of 401, 111, 609, 649 using LCM Formula
Given numbers are 401, 111, 609, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 111) = 44511
GCD(401, 111) = ( 401 x 111 ) / 44511
= 401 / 111
= 401
Step2:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 401, 111, 609, 649 is 1
