Finding GCD of 649, 797, 687 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(649, 797) = 517253

GCD(649, 797) = ( 649 x 797 ) / 517253

GCD(649, 797) = 517253 / 517253

GCD(649, 797) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 687

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

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

GCD(1, 687) = 687 / 687

GCD(1, 687) = 1

GCD of 649, 797, 687 is 1
