Steps to Calculate GCD of 515, 221, 643, 713 using LCM Formula
Given numbers are 515, 221, 643, 713
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 221) = 113815
GCD(515, 221) = ( 515 x 221 ) / 113815
= 515 / 221
= 515
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 713) = 713
GCD(1, 713) = ( 1 x 713 ) / 713
= 1 / 713
= 1
So, Greatest Common Divisor of 515, 221, 643, 713 is 1
