Given Input Data is 280, 425, 393, 325

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

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

Prime Factorization of 425 is 5 x 5 x 17

Prime Factorization of 393 is 3 x 131

Prime Factorization of 325 is 5 x 5 x 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(280, 425) = 23800

GCD(280, 425) = ( 280 x 425 ) / 23800

GCD(280, 425) = 119000 / 23800

GCD(280, 425) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 393

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

LCM(5, 393) = 1965

GCD(5, 393) = ( 5 x 393 ) / 1965

GCD(5, 393) = 1965 / 1965

GCD(5, 393) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 325

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

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

GCD(1, 325) = 325 / 325

GCD(1, 325) = 1

GCD of 280, 425, 393, 325 is 1
