Steps to Calculate GCD of 117, 102, 111, 221 using LCM Formula
Given numbers are 117, 102, 111, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(117, 102) = 3978
GCD(117, 102) = ( 117 x 102 ) / 3978
= 117 / 102
= 117
Step2:
LCM(3, 111) = 111
GCD(3, 111) = ( 3 x 111 ) / 111
= 3 / 111
= 3
Step3:
LCM(3, 221) = 663
GCD(3, 221) = ( 3 x 221 ) / 663
= 3 / 221
= 3
So, Greatest Common Divisor of 117, 102, 111, 221 is 1
