Given Input Data is 395, 490, 848, 781

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

Prime Factorization of 395 is 5 x 79

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

Prime Factorization of 848 is 2 x 2 x 2 x 2 x 53

Prime Factorization of 781 is 11 x 71

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(395, 490) = 38710

GCD(395, 490) = ( 395 x 490 ) / 38710

GCD(395, 490) = 193550 / 38710

GCD(395, 490) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 848

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

LCM(5, 848) = 4240

GCD(5, 848) = ( 5 x 848 ) / 4240

GCD(5, 848) = 4240 / 4240

GCD(5, 848) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 781

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

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

GCD(1, 781) = 781 / 781

GCD(1, 781) = 1

GCD of 395, 490, 848, 781 is 1
