Greatest Common Divisior

We found the divisors of 70, 1, 97, 13 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 70, 1, 97, 13 is 1.

Therefore, GCD of numbers 70, 1, 97, 13 is 1

Given Input Data is 70, 1, 97, 13

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 1 is

Prime Factorization of 97 is 97

Prime Factorization of 13 is 13

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, 1) = 70

GCD(70, 1) = ( 70 x 1 ) / 70

GCD(70, 1) = 70 / 70

GCD(70, 1) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 97

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

LCM(1, 97) = 97

GCD(1, 97) = ( 1 x 97 ) / 97

GCD(1, 97) = 97 / 97

GCD(1, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 13

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

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

GCD(1, 13) = 13 / 13

GCD(1, 13) = 1

GCD of 70, 1, 97, 13 is 1
