Steps to Calculate GCD of 813, 243, 171, 104 using LCM Formula

Given numbers are 813, 243, 171, 104

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(813, 243) = 65853

GCD(813, 243) = ( 813 x 243 ) / 65853

= 813 / 243

= 813


Step2:

LCM(3, 171) = 171

GCD(3, 171) = ( 3 x 171 ) / 171

= 3 / 171

= 3


Step3:

LCM(3, 104) = 312

GCD(3, 104) = ( 3 x 104 ) / 312

= 3 / 104

= 3


So, Greatest Common Divisor of 813, 243, 171, 104 is 1
