Therefore, GCD of numbers 815, 880, 51, 448 is 1

Given Input Data is 815, 880, 51, 448

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

Prime Factorization of 815 is 5 x 163

Prime Factorization of 880 is 2 x 2 x 2 x 2 x 5 x 11

Prime Factorization of 51 is 3 x 17

Prime Factorization of 448 is 2 x 2 x 2 x 2 x 2 x 2 x 7

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(815, 880) = 143440

GCD(815, 880) = ( 815 x 880 ) / 143440

GCD(815, 880) = 717200 / 143440

GCD(815, 880) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 51

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

LCM(5, 51) = 255

GCD(5, 51) = ( 5 x 51 ) / 255

GCD(5, 51) = 255 / 255

GCD(5, 51) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 448

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

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

GCD(1, 448) = 448 / 448

GCD(1, 448) = 1

GCD of 815, 880, 51, 448 is 1
