Greatest Common Divisior

We found the divisors of 38, 17, 69, 74 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 38, 17, 69, 74 is 1.

Therefore, GCD of numbers 38, 17, 69, 74 is 1

Given Input Data is 38, 17, 69, 74

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

Prime Factorization of 38 is 2 x 19

Prime Factorization of 17 is 17

Prime Factorization of 69 is 3 x 23

Prime Factorization of 74 is 2 x 37

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(38, 17) = 646

GCD(38, 17) = ( 38 x 17 ) / 646

GCD(38, 17) = 646 / 646

GCD(38, 17) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 69

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

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

GCD(1, 69) = 69 / 69

GCD(1, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 74

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

LCM(1, 74) = 74

GCD(1, 74) = ( 1 x 74 ) / 74

GCD(1, 74) = 74 / 74

GCD(1, 74) = 1

GCD of 38, 17, 69, 74 is 1
