Steps to Calculate GCD of 169, 489, 18, 169 using LCM Formula
Given numbers are 169, 489, 18, 169
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 489) = 82641
GCD(169, 489) = ( 169 x 489 ) / 82641
= 169 / 489
= 169
Step2:
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
= 1 / 18
= 1
Step3:
LCM(1, 169) = 169
GCD(1, 169) = ( 1 x 169 ) / 169
= 1 / 169
= 1
So, Greatest Common Divisor of 169, 489, 18, 169 is 1
