Greatest Common Divisior

We found the divisors of 69, 9, 39, 67 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 9, 39, 67 is 1.

Therefore, GCD of numbers 69, 9, 39, 67 is 1

Given Input Data is 69, 9, 39, 67

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 9 is 3 x 3

Prime Factorization of 39 is 3 x 13

Prime Factorization of 67 is 67

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(69, 9) = 207

GCD(69, 9) = ( 69 x 9 ) / 207

GCD(69, 9) = 621 / 207

GCD(69, 9) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 39

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

LCM(3, 39) = 39

GCD(3, 39) = ( 3 x 39 ) / 39

GCD(3, 39) = 117 / 39

GCD(3, 39) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 67

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

LCM(3, 67) = 201

GCD(3, 67) = ( 3 x 67 ) / 201

GCD(3, 67) = 201 / 201

GCD(3, 67) = 1

GCD of 69, 9, 39, 67 is 1
