Therefore, GCD of numbers 203, 609, 248, 768 is 1

Given Input Data is 203, 609, 248, 768

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

Prime Factorization of 203 is 7 x 29

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 248 is 2 x 2 x 2 x 31

Prime Factorization of 768 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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(203, 609) = 609

GCD(203, 609) = ( 203 x 609 ) / 609

GCD(203, 609) = 123627 / 609

GCD(203, 609) = 203

Step2:

Here we consider the GCD from the above i.e. 203 as first number and the next as 248

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

LCM(203, 248) = 50344

GCD(203, 248) = ( 203 x 248 ) / 50344

GCD(203, 248) = 50344 / 50344

GCD(203, 248) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 768

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

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

GCD(1, 768) = 768 / 768

GCD(1, 768) = 1

GCD of 203, 609, 248, 768 is 1
