Finding GCD of 864, 663, 647 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(864, 663) = 190944

GCD(864, 663) = ( 864 x 663 ) / 190944

GCD(864, 663) = 572832 / 190944

GCD(864, 663) = 3


Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 647

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

LCM(3, 647) = 1941

GCD(3, 647) = ( 3 x 647 ) / 1941

GCD(3, 647) = 1941 / 1941

GCD(3, 647) = 1

GCD of 864, 663, 647 is 1
