Given Input Data is 490, 584, 385, 245

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

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 584 is 2 x 2 x 2 x 73

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 245 is 5 x 7 x 7

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(490, 584) = 143080

GCD(490, 584) = ( 490 x 584 ) / 143080

GCD(490, 584) = 286160 / 143080

GCD(490, 584) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 385

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

LCM(2, 385) = 770

GCD(2, 385) = ( 2 x 385 ) / 770

GCD(2, 385) = 770 / 770

GCD(2, 385) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

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

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

GCD of 490, 584, 385, 245 is 1
