Steps to Calculate GCD of 171, 989, 171, 638 using LCM Formula
Given numbers are 171, 989, 171, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 989) = 169119
GCD(171, 989) = ( 171 x 989 ) / 169119
= 171 / 989
= 171
Step2:
LCM(1, 171) = 171
GCD(1, 171) = ( 1 x 171 ) / 171
= 1 / 171
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 171, 989, 171, 638 is 1
