Therefore, GCD of numbers 636, 128, 329, 147 is 1

Given Input Data is 636, 128, 329, 147

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 329 is 7 x 47

Prime Factorization of 147 is 3 x 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

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(636, 128) = 20352

GCD(636, 128) = ( 636 x 128 ) / 20352

GCD(636, 128) = 81408 / 20352

GCD(636, 128) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 329

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

LCM(4, 329) = 1316

GCD(4, 329) = ( 4 x 329 ) / 1316

GCD(4, 329) = 1316 / 1316

GCD(4, 329) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 147

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

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

GCD(1, 147) = 147 / 147

GCD(1, 147) = 1

GCD of 636, 128, 329, 147 is 1
