Greatest Common Divisior

We found the divisors of 70, 49, 24 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 70, 49, 24 is 1.

Therefore, GCD of numbers 70, 49, 24 is 1

Given Input Data is 70, 49, 24

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 49 is 7 x 7

Prime Factorization of 24 is 2 x 2 x 2 x 3

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, 49) = 490

GCD(70, 49) = ( 70 x 49 ) / 490

GCD(70, 49) = 3430 / 490

GCD(70, 49) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 24

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

LCM(7, 24) = 168

GCD(7, 24) = ( 7 x 24 ) / 168

GCD(7, 24) = 168 / 168

GCD(7, 24) = 1

GCD of 70, 49, 24 is 1
