JavaScript Challenges

Largest Paliandrome Product

A palindromic number reads the same both ways.

The first argument and only argument sets the requirement for the total digits in a factor.

```
10 is a two-digit number
1996 is a four-digit number
```

1. Find the largest palindrome made from the product of 2 two-digit numbers is 9009 = 91 × 99.
2. Find the largest palindrome made from the product of 2 three-digit numbers. Write two tests that check the return object for the correct factor values.

Do your work in the largestPaliandromeProduct.js file.

Even Fibonacci Numbers

Each new number in the Fibonacci sequence is generated by adding the previous two Fibonacci numbers. For example by starting with the numbers 1 and 2 being the first and second numbers in the Fibonacci sequence, the first 10 numbers in the Fibonacci sequence looks like this:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89

The Exercise You will be given a stub function in the file evenFibNums.js. This function accepts one argument, maxFibValue which is a Number.

Remember, maxFibValue is the max value of a fibonacci number, it is NOT the Nth fibonacci number in the sequence.

You goal will be to sum up all the Even Numbers that are less than or equal to, but does not exceed, the maxFibValue given to you.

Largest Prime Factor

The prime factors of 13195 are 5, 7, 13 and 29.

What is the largest prime factor of the number 600851475143 ?

Do your work in the largestPrimeFactor.js file.
