Therefore, GCD of numbers 205, 128, 57, 483 is 1

Given Input Data is 205, 128, 57, 483

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

Prime Factorization of 205 is 5 x 41

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

Prime Factorization of 57 is 3 x 19

Prime Factorization of 483 is 3 x 7 x 23

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(205, 128) = 26240

GCD(205, 128) = ( 205 x 128 ) / 26240

GCD(205, 128) = 26240 / 26240

GCD(205, 128) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 57

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

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

GCD(1, 57) = 57 / 57

GCD(1, 57) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 483

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

LCM(1, 483) = 483

GCD(1, 483) = ( 1 x 483 ) / 483

GCD(1, 483) = 483 / 483

GCD(1, 483) = 1

GCD of 205, 128, 57, 483 is 1
