Greatest Common Divisior

We found the divisors of 56, 39, 33, 64 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 56, 39, 33, 64 is 1.

Therefore, GCD of numbers 56, 39, 33, 64 is 1

Given Input Data is 56, 39, 33, 64

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

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 39 is 3 x 13

Prime Factorization of 33 is 3 x 11

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

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(56, 39) = 2184

GCD(56, 39) = ( 56 x 39 ) / 2184

GCD(56, 39) = 2184 / 2184

GCD(56, 39) = 1

Step2:

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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 64

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

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

GCD(1, 64) = 64 / 64

GCD(1, 64) = 1

GCD of 56, 39, 33, 64 is 1
