Therefore, GCD of numbers 885, 609, 20, 901 is 1

Given Input Data is 885, 609, 20, 901

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

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 901 is 17 x 53

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(885, 609) = 179655

GCD(885, 609) = ( 885 x 609 ) / 179655

GCD(885, 609) = 538965 / 179655

GCD(885, 609) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 20

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

LCM(3, 20) = 60

GCD(3, 20) = ( 3 x 20 ) / 60

GCD(3, 20) = 60 / 60

GCD(3, 20) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 901

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

LCM(1, 901) = 901

GCD(1, 901) = ( 1 x 901 ) / 901

GCD(1, 901) = 901 / 901

GCD(1, 901) = 1

GCD of 885, 609, 20, 901 is 1
