Greatest Common Divisior

We found the divisors of 46, 7, 20, 13 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 46, 7, 20, 13 is 1.

Therefore, GCD of numbers 46, 7, 20, 13 is 1

Given Input Data is 46, 7, 20, 13

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

Prime Factorization of 46 is 2 x 23

Prime Factorization of 7 is 7

Prime Factorization of 20 is 2 x 2 x 5

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(46, 7) = 322

GCD(46, 7) = ( 46 x 7 ) / 322

GCD(46, 7) = 322 / 322

GCD(46, 7) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 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 46, 7, 20, 13 is 1
