Greatest Common Divisior

We found the divisors of 16, 9, 65, 86 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 16, 9, 65, 86 is 1.

Therefore, GCD of numbers 16, 9, 65, 86 is 1

Given Input Data is 16, 9, 65, 86

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

Prime Factorization of 16 is 2 x 2 x 2 x 2

Prime Factorization of 9 is 3 x 3

Prime Factorization of 65 is 5 x 13

Prime Factorization of 86 is 2 x 43

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(16, 9) = 144

GCD(16, 9) = ( 16 x 9 ) / 144

GCD(16, 9) = 144 / 144

GCD(16, 9) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 65

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

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

GCD(1, 65) = 65 / 65

GCD(1, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 86

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

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

GCD(1, 86) = 86 / 86

GCD(1, 86) = 1

GCD of 16, 9, 65, 86 is 1
