Steps to Calculate GCD of 815, 221, 221, 244 using LCM Formula
Given numbers are 815, 221, 221, 244
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 221) = 180115
GCD(815, 221) = ( 815 x 221 ) / 180115
= 815 / 221
= 815
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
= 1 / 244
= 1
So, Greatest Common Divisor of 815, 221, 221, 244 is 1
