Greatest Common Divisior

We found the divisors of 30, 403, 700, 863 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 403, 700, 863 is 1.

Therefore, GCD of numbers 30, 403, 700, 863 is 1

Given Input Data is 30, 403, 700, 863

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 403 is 13 x 31

Prime Factorization of 700 is 2 x 2 x 5 x 5 x 7

Prime Factorization of 863 is 863

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(30, 403) = 12090

GCD(30, 403) = ( 30 x 403 ) / 12090

GCD(30, 403) = 12090 / 12090

GCD(30, 403) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 700

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

LCM(1, 700) = 700

GCD(1, 700) = ( 1 x 700 ) / 700

GCD(1, 700) = 700 / 700

GCD(1, 700) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 863

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

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

GCD(1, 863) = 863 / 863

GCD(1, 863) = 1

GCD of 30, 403, 700, 863 is 1
