So the Greatest Common Divisior 25, 75, 57 is 1.

Therefore, GCD of numbers 25, 75, 57 is 1

Given Input Data is 25, 75, 57

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

Prime Factorization of 25 is 5 x 5

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 57 is 3 x 19

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(25, 75) = 75

GCD(25, 75) = ( 25 x 75 ) / 75

GCD(25, 75) = 1875 / 75

GCD(25, 75) = 25

Step2:

Here we consider the GCD from the above i.e. 25 as first number and the next as 57

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

LCM(25, 57) = 1425

GCD(25, 57) = ( 25 x 57 ) / 1425

GCD(25, 57) = 1425 / 1425

GCD(25, 57) = 1

GCD of 25, 75, 57 is 1
