Steps to Calculate GCD of 173, 242, 459, 643 using LCM Formula
Given numbers are 173, 242, 459, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(173, 242) = 41866
GCD(173, 242) = ( 173 x 242 ) / 41866
= 173 / 242
= 173
Step2:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 173, 242, 459, 643 is 1
