Greatest Common Divisior

We found the divisors of 10, 99, 69 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 10, 99, 69 is 1.

Therefore, GCD of numbers 10, 99, 69 is 1

Given Input Data is 10, 99, 69

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

Prime Factorization of 10 is 2 x 5

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 69 is 3 x 23

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(10, 99) = 990

GCD(10, 99) = ( 10 x 99 ) / 990

GCD(10, 99) = 990 / 990

GCD(10, 99) = 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

GCD of 10, 99, 69 is 1
