Greatest Common Divisior

We found the divisors of 806, 805, 40, 503 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 806, 805, 40, 503 is 1.

Therefore, GCD of numbers 806, 805, 40, 503 is 1

Given Input Data is 806, 805, 40, 503

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

Prime Factorization of 806 is 2 x 13 x 31

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 503 is 503

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(806, 805) = 648830

GCD(806, 805) = ( 806 x 805 ) / 648830

GCD(806, 805) = 648830 / 648830

GCD(806, 805) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 503

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

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

GCD(1, 503) = 503 / 503

GCD(1, 503) = 1

GCD of 806, 805, 40, 503 is 1
