Greatest Common Divisior

We found the divisors of 33, 5, 15, 63 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 33, 5, 15, 63 is 1.

Therefore, GCD of numbers 33, 5, 15, 63 is 1

Given Input Data is 33, 5, 15, 63

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

Prime Factorization of 33 is 3 x 11

Prime Factorization of 5 is 5

Prime Factorization of 15 is 3 x 5

Prime Factorization of 63 is 3 x 3 x 7

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(33, 5) = 165

GCD(33, 5) = ( 33 x 5 ) / 165

GCD(33, 5) = 165 / 165

GCD(33, 5) = 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 63

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

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

GCD(1, 63) = 63 / 63

GCD(1, 63) = 1

GCD of 33, 5, 15, 63 is 1
