Finding GCD of 639, 555, 458 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(639, 555) = 118215

GCD(639, 555) = ( 639 x 555 ) / 118215

GCD(639, 555) = 354645 / 118215

GCD(639, 555) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 458

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

LCM(3, 458) = 1374

GCD(3, 458) = ( 3 x 458 ) / 1374

GCD(3, 458) = 1374 / 1374

GCD(3, 458) = 1

GCD of 639, 555, 458 is 1
