Given Input Data is 428, 448, 445

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

Prime Factorization of 428 is 2 x 2 x 107

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

Prime Factorization of 445 is 5 x 89

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(428, 448) = 47936

GCD(428, 448) = ( 428 x 448 ) / 47936

GCD(428, 448) = 191744 / 47936

GCD(428, 448) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 445

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

LCM(4, 445) = 1780

GCD(4, 445) = ( 4 x 445 ) / 1780

GCD(4, 445) = 1780 / 1780

GCD(4, 445) = 1

GCD of 428, 448, 445 is 1
