Therefore, GCD of numbers 450, 310, 25, 406 is 1

Given Input Data is 450, 310, 25, 406

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

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 310 is 2 x 5 x 31

Prime Factorization of 25 is 5 x 5

Prime Factorization of 406 is 2 x 7 x 29

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(450, 310) = 13950

GCD(450, 310) = ( 450 x 310 ) / 13950

GCD(450, 310) = 139500 / 13950

GCD(450, 310) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 25

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

LCM(10, 25) = 50

GCD(10, 25) = ( 10 x 25 ) / 50

GCD(10, 25) = 250 / 50

GCD(10, 25) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 406

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

LCM(5, 406) = 2030

GCD(5, 406) = ( 5 x 406 ) / 2030

GCD(5, 406) = 2030 / 2030

GCD(5, 406) = 1

GCD of 450, 310, 25, 406 is 1
