Therefore, GCD of numbers 215, 525, 25, 459 is 1

Given Input Data is 215, 525, 25, 459

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 525 is 3 x 5 x 5 x 7

Prime Factorization of 25 is 5 x 5

Prime Factorization of 459 is 3 x 3 x 3 x 17

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(215, 525) = 22575

GCD(215, 525) = ( 215 x 525 ) / 22575

GCD(215, 525) = 112875 / 22575

GCD(215, 525) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 25

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

LCM(5, 25) = 25

GCD(5, 25) = ( 5 x 25 ) / 25

GCD(5, 25) = 125 / 25

GCD(5, 25) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 459

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

LCM(5, 459) = 2295

GCD(5, 459) = ( 5 x 459 ) / 2295

GCD(5, 459) = 2295 / 2295

GCD(5, 459) = 1

GCD of 215, 525, 25, 459 is 1
