Greatest Common Divisior

We found the divisors of 51, 80, 43 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 51, 80, 43 is 1.

Therefore, GCD of numbers 51, 80, 43 is 1

Given Input Data is 51, 80, 43

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 43 is 43

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(51, 80) = 4080

GCD(51, 80) = ( 51 x 80 ) / 4080

GCD(51, 80) = 4080 / 4080

GCD(51, 80) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 43

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

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

GCD(1, 43) = 43 / 43

GCD(1, 43) = 1

GCD of 51, 80, 43 is 1
