Therefore, GCD of numbers 244, 961, 20, 190 is 1

Given Input Data is 244, 961, 20, 190

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

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 961 is 31 x 31

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 190 is 2 x 5 x 19

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(244, 961) = 234484

GCD(244, 961) = ( 244 x 961 ) / 234484

GCD(244, 961) = 234484 / 234484

GCD(244, 961) = 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 190

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

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

GCD(1, 190) = 190 / 190

GCD(1, 190) = 1

GCD of 244, 961, 20, 190 is 1
