Steps to Calculate GCD of 103, 986, 421, 155 using LCM Formula
Given numbers are 103, 986, 421, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(103, 986) = 101558
GCD(103, 986) = ( 103 x 986 ) / 101558
= 103 / 986
= 103
Step2:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 103, 986, 421, 155 is 1
