Greatest Common Divisior

We found the divisors of 19, 305, 400, 653 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 305, 400, 653 is 1.

Therefore, GCD of numbers 19, 305, 400, 653 is 1

Given Input Data is 19, 305, 400, 653

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

Prime Factorization of 19 is 19

Prime Factorization of 305 is 5 x 61

Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 653 is 653

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(19, 305) = 5795

GCD(19, 305) = ( 19 x 305 ) / 5795

GCD(19, 305) = 5795 / 5795

GCD(19, 305) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 400

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

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

GCD(1, 400) = 400 / 400

GCD(1, 400) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 653

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

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

GCD(1, 653) = 653 / 653

GCD(1, 653) = 1

GCD of 19, 305, 400, 653 is 1
