Therefore, GCD of numbers 715, 520, 409, 520 is 1

Given Input Data is 715, 520, 409, 520

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 409 is 409

Prime Factorization of 520 is 2 x 2 x 2 x 5 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(715, 520) = 5720

GCD(715, 520) = ( 715 x 520 ) / 5720

GCD(715, 520) = 371800 / 5720

GCD(715, 520) = 65

Step2:

Here we consider the GCD from the above i.e. 65 as first number and the next as 409

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

LCM(65, 409) = 26585

GCD(65, 409) = ( 65 x 409 ) / 26585

GCD(65, 409) = 26585 / 26585

GCD(65, 409) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 520

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

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

GCD(1, 520) = 520 / 520

GCD(1, 520) = 1

GCD of 715, 520, 409, 520 is 1
