Steps to Calculate GCD of 291, 171, 489, 223 using LCM Formula
Given numbers are 291, 171, 489, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 171) = 16587
GCD(291, 171) = ( 291 x 171 ) / 16587
= 291 / 171
= 291
Step2:
LCM(3, 489) = 489
GCD(3, 489) = ( 3 x 489 ) / 489
= 3 / 489
= 3
Step3:
LCM(3, 223) = 669
GCD(3, 223) = ( 3 x 223 ) / 669
= 3 / 223
= 3
So, Greatest Common Divisor of 291, 171, 489, 223 is 1
