Greatest Common Divisior

We found the divisors of 19, 300, 542, 640 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 300, 542, 640 is 1.

Therefore, GCD of numbers 19, 300, 542, 640 is 1

Given Input Data is 19, 300, 542, 640

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

Prime Factorization of 19 is 19

Prime Factorization of 300 is 2 x 2 x 3 x 5 x 5

Prime Factorization of 542 is 2 x 271

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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, 300) = 5700

GCD(19, 300) = ( 19 x 300 ) / 5700

GCD(19, 300) = 5700 / 5700

GCD(19, 300) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 542

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

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

GCD(1, 542) = 542 / 542

GCD(1, 542) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 640

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

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

GCD(1, 640) = 640 / 640

GCD(1, 640) = 1

GCD of 19, 300, 542, 640 is 1
