Steps to Calculate GCD of 401, 628, 129, 694 using LCM Formula
Given numbers are 401, 628, 129, 694
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 628) = 251828
GCD(401, 628) = ( 401 x 628 ) / 251828
= 401 / 628
= 401
Step2:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 401, 628, 129, 694 is 1
