Steps to Calculate GCD of 813, 638, 252, 580 using LCM Formula

Given numbers are 813, 638, 252, 580

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

Apply this formula for all numbers.

Step1:

LCM(813, 638) = 518694

GCD(813, 638) = ( 813 x 638 ) / 518694

= 813 / 638

= 813


Step2:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1


Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1


So, Greatest Common Divisor of 813, 638, 252, 580 is 1
