Therefore, GCD of numbers 515, 605, 797, 715 is 1

Given Input Data is 515, 605, 797, 715

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

Prime Factorization of 515 is 5 x 103

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 797 is 797

Prime Factorization of 715 is 5 x 11 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(515, 605) = 62315

GCD(515, 605) = ( 515 x 605 ) / 62315

GCD(515, 605) = 311575 / 62315

GCD(515, 605) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 797

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

LCM(5, 797) = 3985

GCD(5, 797) = ( 5 x 797 ) / 3985

GCD(5, 797) = 3985 / 3985

GCD(5, 797) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 715

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

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

GCD(1, 715) = 715 / 715

GCD(1, 715) = 1

GCD of 515, 605, 797, 715 is 1
