Steps to Calculate GCD of 291, 653, 878, 129 using LCM Formula
Given numbers are 291, 653, 878, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 653) = 190023
GCD(291, 653) = ( 291 x 653 ) / 190023
= 291 / 653
= 291
Step2:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 291, 653, 878, 129 is 1
