Therefore, GCD of numbers 285, 825, 47, 425 is 1

Given Input Data is 285, 825, 47, 425

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

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 825 is 3 x 5 x 5 x 11

Prime Factorization of 47 is 47

Prime Factorization of 425 is 5 x 5 x 17

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(285, 825) = 15675

GCD(285, 825) = ( 285 x 825 ) / 15675

GCD(285, 825) = 235125 / 15675

GCD(285, 825) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 47

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

LCM(15, 47) = 705

GCD(15, 47) = ( 15 x 47 ) / 705

GCD(15, 47) = 705 / 705

GCD(15, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 425

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

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

GCD(1, 425) = 425 / 425

GCD(1, 425) = 1

GCD of 285, 825, 47, 425 is 1
