Greatest Common Divisior

We found the divisors of 25, 72, 25, 53 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 25, 72, 25, 53 is 1.

Therefore, GCD of numbers 25, 72, 25, 53 is 1

Given Input Data is 25, 72, 25, 53

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

Prime Factorization of 25 is 5 x 5

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 25 is 5 x 5

Prime Factorization of 53 is 53

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, 72) = 1800

GCD(25, 72) = ( 25 x 72 ) / 1800

GCD(25, 72) = 1800 / 1800

GCD(25, 72) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 25

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

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

GCD(1, 25) = 25 / 25

GCD(1, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 53

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

LCM(1, 53) = 53

GCD(1, 53) = ( 1 x 53 ) / 53

GCD(1, 53) = 53 / 53

GCD(1, 53) = 1

GCD of 25, 72, 25, 53 is 1
