How To Find Multiplication Factors of a negative number

October 30, 2022

I wanna find the factors of a negative number in multiplication

Somethings not right on my method, it only works on positive numbers not negative

I have this and it did not work with negative numbers

function factorMul(num) {

  let tryThis1 = Math.floor(

    Math.random() * (num - 1 + 1) + 1

  )

  let tryThis2 = Math.floor(

    Math.random() * (num - 1 + 1) + 1

  )

  if(Math.floor(tryThis1 * tryThis2) !== num) return factorMul(num)

  return [tryThis1, tryThis2]

}

When i tried it with negative numbers i got maximum call stack size

>Solution :

Find Multiplication Factors of a negative number:

Essentially, to factor a negative number, find all of its positive
factors, then duplicate them and write a negative sign in front of
the duplicates. For instance, the positive factors of −3 are 1 and 3.
Duplicating them produces 1, 3, 1, 3; writing a negative sign before
the duplicates produces 1, 3, −1, −3, which are all of the factors of
−3.

So, in your code, just check if the number passed is negative, if it was, make it positive, then when it is ready to return the values, do the hint above.
