Given Input Data is 490, 240, 647, 301

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 240 is 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 647 is 647

Prime Factorization of 301 is 7 x 43

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, 240) = 11760

GCD(490, 240) = ( 490 x 240 ) / 11760

GCD(490, 240) = 117600 / 11760

GCD(490, 240) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 647

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

LCM(10, 647) = 6470

GCD(10, 647) = ( 10 x 647 ) / 6470

GCD(10, 647) = 6470 / 6470

GCD(10, 647) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 301

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

LCM(1, 301) = 301

GCD(1, 301) = ( 1 x 301 ) / 301

GCD(1, 301) = 301 / 301

GCD(1, 301) = 1

GCD of 490, 240, 647, 301 is 1
