Greatest Common Divisior

We found the divisors of 69, 8, 78, 33 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 8, 78, 33 is 1.

Therefore, GCD of numbers 69, 8, 78, 33 is 1

Given Input Data is 69, 8, 78, 33

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 8 is 2 x 2 x 2

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 33 is 3 x 11

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, 8) = 552

GCD(69, 8) = ( 69 x 8 ) / 552

GCD(69, 8) = 552 / 552

GCD(69, 8) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

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

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 33

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

LCM(1, 33) = 33

GCD(1, 33) = ( 1 x 33 ) / 33

GCD(1, 33) = 33 / 33

GCD(1, 33) = 1

GCD of 69, 8, 78, 33 is 1
