Greatest Common Divisior

We found the divisors of 43, 28, 64 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 43, 28, 64 is 1.

Therefore, GCD of numbers 43, 28, 64 is 1

Given Input Data is 43, 28, 64

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

Prime Factorization of 43 is 43

Prime Factorization of 28 is 2 x 2 x 7

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(43, 28) = 1204

GCD(43, 28) = ( 43 x 28 ) / 1204

GCD(43, 28) = 1204 / 1204

GCD(43, 28) = 1

Step2:

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 43, 28, 64 is 1
