Greatest Common Divisior

We found the divisors of 74, 72, 25 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 74, 72, 25 is 1.

Therefore, GCD of numbers 74, 72, 25 is 1

Given Input Data is 74, 72, 25

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

Prime Factorization of 74 is 2 x 37

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

Prime Factorization of 25 is 5 x 5

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(74, 72) = 2664

GCD(74, 72) = ( 74 x 72 ) / 2664

GCD(74, 72) = 5328 / 2664

GCD(74, 72) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 25

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

LCM(2, 25) = 50

GCD(2, 25) = ( 2 x 25 ) / 50

GCD(2, 25) = 50 / 50

GCD(2, 25) = 1

GCD of 74, 72, 25 is 1
