Greatest Common Divisior

We found the divisors of 32, 478, 128, 165 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 32, 478, 128, 165 is 1.

Therefore, GCD of numbers 32, 478, 128, 165 is 1

Given Input Data is 32, 478, 128, 165

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

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

Prime Factorization of 478 is 2 x 239

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 165 is 3 x 5 x 11

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(32, 478) = 7648

GCD(32, 478) = ( 32 x 478 ) / 7648

GCD(32, 478) = 15296 / 7648

GCD(32, 478) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 128

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

LCM(2, 128) = 128

GCD(2, 128) = ( 2 x 128 ) / 128

GCD(2, 128) = 256 / 128

GCD(2, 128) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 165

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

LCM(2, 165) = 330

GCD(2, 165) = ( 2 x 165 ) / 330

GCD(2, 165) = 330 / 330

GCD(2, 165) = 1

GCD of 32, 478, 128, 165 is 1
