Therefore, GCD of numbers 15, 375, 521, 805 is 1

Given Input Data is 15, 375, 521, 805

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 375 is 3 x 5 x 5 x 5

Prime Factorization of 521 is 521

Prime Factorization of 805 is 5 x 7 x 23

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(15, 375) = 375

GCD(15, 375) = ( 15 x 375 ) / 375

GCD(15, 375) = 5625 / 375

GCD(15, 375) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 521

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

LCM(15, 521) = 7815

GCD(15, 521) = ( 15 x 521 ) / 7815

GCD(15, 521) = 7815 / 7815

GCD(15, 521) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 805

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

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

GCD(1, 805) = 805 / 805

GCD(1, 805) = 1

GCD of 15, 375, 521, 805 is 1
