Therefore, GCD of numbers 245, 200, 86, 809 is 1

Given Input Data is 245, 200, 86, 809

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 200 is 2 x 2 x 2 x 5 x 5

Prime Factorization of 86 is 2 x 43

Prime Factorization of 809 is 809

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(245, 200) = 9800

GCD(245, 200) = ( 245 x 200 ) / 9800

GCD(245, 200) = 49000 / 9800

GCD(245, 200) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 86

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

LCM(5, 86) = 430

GCD(5, 86) = ( 5 x 86 ) / 430

GCD(5, 86) = 430 / 430

GCD(5, 86) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 809

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

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

GCD(1, 809) = 809 / 809

GCD(1, 809) = 1

GCD of 245, 200, 86, 809 is 1
