Given numbers are 615, 618, 812

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

Apply this formula for all numbers.

Step1:

LCM(615, 618) = 126690

GCD(615, 618) = ( 615 x 618 ) / 126690

= 615 / 618

= 615

Step2:

LCM(3, 812) = 2436

GCD(3, 812) = ( 3 x 812 ) / 2436

= 3 / 812

= 3

So, Greatest Common Divisor of 615, 618, 812 is 1
