Finding GCD of 640, 328, 486 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(640, 328) = 26240

GCD(640, 328) = ( 640 x 328 ) / 26240

GCD(640, 328) = 209920 / 26240

GCD(640, 328) = 8


Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 486

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

LCM(8, 486) = 1944

GCD(8, 486) = ( 8 x 486 ) / 1944

GCD(8, 486) = 3888 / 1944

GCD(8, 486) = 2

GCD of 640, 328, 486 is 2
