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

Largest prime factor

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

## What is the largest prime factor of the number 600851475143 in Javascript?

log(highestPrimeFactor(600851475143)); The answer is: 6857. Since every integer can be represented (factored) using prime numbers like 2^a*3^b*5^c…. We can skip the prime number tests and just use a simple loop to find the largest prime factor.

## How do you find the largest prime factor?

To find the greatest common divisor (GCF) between numbers, take each number and write its prime factorization. Then identify the factors common to each number and multiply those common factors. bam! The FCG!

## Is the prime number JavaScript?

Prime numbers are never even (except 2). In JavaScript, we can check for even numbers using the modulus operator (%). The modulus operator returns the remainder after dividing one integer by another. For example, 12% 5 returns 2.

## 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.

## What is the largest prime factor of 13195?

The prime factors of 13195 are 5, 7, 13, and 29. What is the greatest prime factor of the number 600851475143? Most of the answers I found made use of array to store the prime factors and iterate over them to find the largest which doesn’t look good. I’m recently learning js and this doesn’t seem like a way to do javascript to me.

## What is the greatest prime factor of the number 60085?

What is the greatest prime factor of the number 600851475143?
