Steps to Calculate GCD of 103, 209, 655, 556 using LCM Formula
Given numbers are 103, 209, 655, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(103, 209) = 21527
GCD(103, 209) = ( 103 x 209 ) / 21527
= 103 / 209
= 103
Step2:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 103, 209, 655, 556 is 1
