Steps to Calculate GCD of 221, 220, 220, 387 using LCM Formula
Given numbers are 221, 220, 220, 387
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 220) = 48620
GCD(221, 220) = ( 221 x 220 ) / 48620
= 221 / 220
= 221
Step2:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
Step3:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
So, Greatest Common Divisor of 221, 220, 220, 387 is 1
