Therefore, GCD of numbers 432, 783, 15, 425 is 1

Given Input Data is 432, 783, 15, 425

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

Prime Factorization of 432 is 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 15 is 3 x 5

Prime Factorization of 425 is 5 x 5 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(432, 783) = 12528

GCD(432, 783) = ( 432 x 783 ) / 12528

GCD(432, 783) = 338256 / 12528

GCD(432, 783) = 27

Step2:

Here we consider the GCD from the above i.e. 27 as first number and the next as 15

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

LCM(27, 15) = 135

GCD(27, 15) = ( 27 x 15 ) / 135

GCD(27, 15) = 405 / 135

GCD(27, 15) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 425

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

LCM(3, 425) = 1275

GCD(3, 425) = ( 3 x 425 ) / 1275

GCD(3, 425) = 1275 / 1275

GCD(3, 425) = 1

GCD of 432, 783, 15, 425 is 1
