Therefore, GCD of numbers 445, 280, 36, 113 is 1

Given Input Data is 445, 280, 36, 113

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

Prime Factorization of 445 is 5 x 89

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 113 is 113

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(445, 280) = 24920

GCD(445, 280) = ( 445 x 280 ) / 24920

GCD(445, 280) = 124600 / 24920

GCD(445, 280) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 36

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

LCM(5, 36) = 180

GCD(5, 36) = ( 5 x 36 ) / 180

GCD(5, 36) = 180 / 180

GCD(5, 36) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 113

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

LCM(1, 113) = 113

GCD(1, 113) = ( 1 x 113 ) / 113

GCD(1, 113) = 113 / 113

GCD(1, 113) = 1

GCD of 445, 280, 36, 113 is 1
