Finding GCD of 817, 858, 609 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

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

LCM(817, 858) = 700986

GCD(817, 858) = ( 817 x 858 ) / 700986

GCD(817, 858) = 700986 / 700986

GCD(817, 858) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 609

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

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

GCD(1, 609) = 609 / 609

GCD(1, 609) = 1

GCD of 817, 858, 609 is 1
