Finding GCD of 638, 308, 263 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(638, 308) = 8932

GCD(638, 308) = ( 638 x 308 ) / 8932

GCD(638, 308) = 196504 / 8932

GCD(638, 308) = 22

Step2:

Here we consider the GCD from the above i.e. 22 as first number and the next as 263

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

LCM(22, 263) = 5786

GCD(22, 263) = ( 22 x 263 ) / 5786

GCD(22, 263) = 5786 / 5786

GCD(22, 263) = 1

GCD of 638, 308, 263 is 1
