The sum of the squares of the first ten natural numbers is,

`1^2 + 2^2 + ... + 10^2 = 385`

The square of the sum of the first ten natural numbers is,

`(1 + 2 + ... + 10)^2 = 552 = 3025`

Hence the difference between the sum of the...

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.

What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

**This is the fastest and shortest...

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

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

By considering the terms in the Fibonacci sequence whose v...

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

It has always been fun for me to play with mathematic prob...
