Finding GCD of 643, 164, 474 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(643, 164) = 105452

GCD(643, 164) = ( 643 x 164 ) / 105452

GCD(643, 164) = 105452 / 105452

GCD(643, 164) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 474

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

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

GCD(1, 474) = 474 / 474

GCD(1, 474) = 1

GCD of 643, 164, 474 is 1
