Finding GCD of 676, 390, 423 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(676, 390) = 10140

GCD(676, 390) = ( 676 x 390 ) / 10140

GCD(676, 390) = 263640 / 10140

GCD(676, 390) = 26

Step2:

Here we consider the GCD from the above i.e. 26 as first number and the next as 423

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

LCM(26, 423) = 10998

GCD(26, 423) = ( 26 x 423 ) / 10998

GCD(26, 423) = 10998 / 10998

GCD(26, 423) = 1

GCD of 676, 390, 423 is 1
