Therefore, GCD of numbers 672, 424, 50, 261 is 1

Given Input Data is 672, 424, 50, 261

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

Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 261 is 3 x 3 x 29

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(672, 424) = 35616

GCD(672, 424) = ( 672 x 424 ) / 35616

GCD(672, 424) = 284928 / 35616

GCD(672, 424) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 50

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

LCM(8, 50) = 200

GCD(8, 50) = ( 8 x 50 ) / 200

GCD(8, 50) = 400 / 200

GCD(8, 50) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 261

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

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

GCD(2, 261) = 522 / 522

GCD(2, 261) = 1

GCD of 672, 424, 50, 261 is 1
