Steps to Calculate GCD of 812, 605, 459, 123 using LCM Formula

Given numbers are 812, 605, 459, 123

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

Apply this formula for all numbers.

Step1:

LCM(812, 605) = 491260

GCD(812, 605) = ( 812 x 605 ) / 491260

= 812 / 605

= 812


Step2:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1


Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1


So, Greatest Common Divisor of 812, 605, 459, 123 is 1
