Greatest Common Divisior

We found the divisors of 41, 42, 39, 30 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 41, 42, 39, 30 is 1.

Therefore, GCD of numbers 41, 42, 39, 30 is 1

Given Input Data is 41, 42, 39, 30

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

Prime Factorization of 41 is 41

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 39 is 3 x 13

Prime Factorization of 30 is 2 x 3 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(41, 42) = 1722

GCD(41, 42) = ( 41 x 42 ) / 1722

GCD(41, 42) = 1722 / 1722

GCD(41, 42) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 39

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

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

GCD(1, 39) = 39 / 39

GCD(1, 39) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 30

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

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

GCD(1, 30) = 30 / 30

GCD(1, 30) = 1

GCD of 41, 42, 39, 30 is 1
