Greatest Common Divisior

We found the divisors of 17, 66, 15, 46 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 17, 66, 15, 46 is 1.

Therefore, GCD of numbers 17, 66, 15, 46 is 1

Given Input Data is 17, 66, 15, 46

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

Prime Factorization of 17 is 17

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 15 is 3 x 5

Prime Factorization of 46 is 2 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(17, 66) = 1122

GCD(17, 66) = ( 17 x 66 ) / 1122

GCD(17, 66) = 1122 / 1122

GCD(17, 66) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 46

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

LCM(1, 46) = 46

GCD(1, 46) = ( 1 x 46 ) / 46

GCD(1, 46) = 46 / 46

GCD(1, 46) = 1

GCD of 17, 66, 15, 46 is 1
