Steps to Calculate GCD of 115, 643, 220, 339 using LCM Formula
Given numbers are 115, 643, 220, 339
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 643) = 73945
GCD(115, 643) = ( 115 x 643 ) / 73945
= 115 / 643
= 115
Step2:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
Step3:
LCM(1, 339) = 339
GCD(1, 339) = ( 1 x 339 ) / 339
= 1 / 339
= 1
So, Greatest Common Divisor of 115, 643, 220, 339 is 1
