Steps to Calculate GCD of 218, 665, 163, 231 using LCM Formula
Given numbers are 218, 665, 163, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 665) = 144970
GCD(218, 665) = ( 218 x 665 ) / 144970
= 218 / 665
= 218
Step2:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 218, 665, 163, 231 is 1
