Therefore, GCD of numbers 207, 805, 98, 517 is 1

Given Input Data is 207, 805, 98, 517

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 517 is 11 x 47

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(207, 805) = 7245

GCD(207, 805) = ( 207 x 805 ) / 7245

GCD(207, 805) = 166635 / 7245

GCD(207, 805) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 98

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

LCM(23, 98) = 2254

GCD(23, 98) = ( 23 x 98 ) / 2254

GCD(23, 98) = 2254 / 2254

GCD(23, 98) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 517

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

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

GCD(1, 517) = 517 / 517

GCD(1, 517) = 1

GCD of 207, 805, 98, 517 is 1
