Therefore, GCD of numbers 195, 249, 48, 787 is 1

Given Input Data is 195, 249, 48, 787

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

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 249 is 3 x 83

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 787 is 787

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(195, 249) = 16185

GCD(195, 249) = ( 195 x 249 ) / 16185

GCD(195, 249) = 48555 / 16185

GCD(195, 249) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 48

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

LCM(3, 48) = 48

GCD(3, 48) = ( 3 x 48 ) / 48

GCD(3, 48) = 144 / 48

GCD(3, 48) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 787

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

LCM(3, 787) = 2361

GCD(3, 787) = ( 3 x 787 ) / 2361

GCD(3, 787) = 2361 / 2361

GCD(3, 787) = 1

GCD of 195, 249, 48, 787 is 1
