Given Input Data is 445, 765, 560, 177

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

Prime Factorization of 445 is 5 x 89

Prime Factorization of 765 is 3 x 3 x 5 x 17

Prime Factorization of 560 is 2 x 2 x 2 x 2 x 5 x 7

Prime Factorization of 177 is 3 x 59

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(445, 765) = 68085

GCD(445, 765) = ( 445 x 765 ) / 68085

GCD(445, 765) = 340425 / 68085

GCD(445, 765) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 560

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

LCM(5, 560) = 560

GCD(5, 560) = ( 5 x 560 ) / 560

GCD(5, 560) = 2800 / 560

GCD(5, 560) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 177

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

LCM(5, 177) = 885

GCD(5, 177) = ( 5 x 177 ) / 885

GCD(5, 177) = 885 / 885

GCD(5, 177) = 1

GCD of 445, 765, 560, 177 is 1
