Greatest Common Divisior

We found the divisors of 70, 25, 74 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 70, 25, 74 is 1.

Therefore, GCD of numbers 70, 25, 74 is 1

Given Input Data is 70, 25, 74

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 25 is 5 x 5

Prime Factorization of 74 is 2 x 37

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(70, 25) = 350

GCD(70, 25) = ( 70 x 25 ) / 350

GCD(70, 25) = 1750 / 350

GCD(70, 25) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 74

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

LCM(5, 74) = 370

GCD(5, 74) = ( 5 x 74 ) / 370

GCD(5, 74) = 370 / 370

GCD(5, 74) = 1

GCD of 70, 25, 74 is 1
