Therefore, GCD of numbers 230, 300, 478, 745 is 1

Given Input Data is 230, 300, 478, 745

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

Prime Factorization of 230 is 2 x 5 x 23

Prime Factorization of 300 is 2 x 2 x 3 x 5 x 5

Prime Factorization of 478 is 2 x 239

Prime Factorization of 745 is 5 x 149

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(230, 300) = 6900

GCD(230, 300) = ( 230 x 300 ) / 6900

GCD(230, 300) = 69000 / 6900

GCD(230, 300) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 478

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

LCM(10, 478) = 2390

GCD(10, 478) = ( 10 x 478 ) / 2390

GCD(10, 478) = 4780 / 2390

GCD(10, 478) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 745

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

LCM(2, 745) = 1490

GCD(2, 745) = ( 2 x 745 ) / 1490

GCD(2, 745) = 1490 / 1490

GCD(2, 745) = 1

GCD of 230, 300, 478, 745 is 1
