Steps to Calculate GCD of 129, 129, 956, 438 using LCM Formula
Given numbers are 129, 129, 956, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 129) = 129
GCD(129, 129) = ( 129 x 129 ) / 129
= 129 / 129
= 129
Step2:
LCM(129, 956) = 123324
GCD(129, 956) = ( 129 x 956 ) / 123324
= 129 / 956
= 129
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 129, 129, 956, 438 is 1
