How do you find the largest prime factor of a number in Javascript?

How do you find the largest prime factor of a number in Javascript?

Largest prime factor

  1. Example 1 ~ 12: First things first, divide the number (12 in this example) with the smallest prime number, which is 2: 12/2 = 6.
  2. Example 2 ~ 20: Repeating the same steps as in our first example: 20 / 2 = 10.
  3. Example 3 ~ 180. 180 / 2 = 90. 90 / 2 = 45.

How to find the largest prime factor of a number?

I am looking for a way to return the largest prime factor of a given number. My first instinct was to work with a while loop that counts and finds the prime factors of the number, stores the factors in an array, and restarts each time it finds one. In this way, the last element of the matrix must be the largest prime factor.
