Steps to Calculate GCD of 813, 349, 643, 427 using LCM Formula

Given numbers are 813, 349, 643, 427

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

Apply this formula for all numbers.

Step1:

LCM(813, 349) = 283737

GCD(813, 349) = ( 813 x 349 ) / 283737

= 813 / 349

= 813


Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1


Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1
