Greatest Common Divisior

We found the divisors of 66, 57, 16 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 66, 57, 16 is 1.

Therefore, GCD of numbers 66, 57, 16 is 1

Given Input Data is 66, 57, 16

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 57 is 3 x 19

Prime Factorization of 16 is 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(66, 57) = 1254

GCD(66, 57) = ( 66 x 57 ) / 1254

GCD(66, 57) = 3762 / 1254

GCD(66, 57) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 16

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

LCM(3, 16) = 48

GCD(3, 16) = ( 3 x 16 ) / 48

GCD(3, 16) = 48 / 48

GCD(3, 16) = 1

GCD of 66, 57, 16 is 1
