Steps to Calculate GCD of 979, 921, 965, 155 using LCM Formula
Given numbers are 979, 921, 965, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(979, 921) = 901659
GCD(979, 921) = ( 979 x 921 ) / 901659
= 979 / 921
= 979
Step2:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 979, 921, 965, 155 is 1
