    my $default_answer = $p5->solve;

DESCRIPTION

This module is used to solve problem #005

Use Math::BigInt to calculate the least common multiple between numbers

SETUP

Problem Number

    005

Problem Name

    Least common multiple

Problem Date

    30 November 2001

Problem Desc

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

Default Input

20

Default Answer

    232792560

Has Input?

    Yes

Help Message

The input controls the cap of the range of numbers to find the least common multiple of.

INTERNAL FUNCTIONS

Validate Input

The restrictions on custom_input

    A positve integer

Solving the problem

This is just goes from the largest multi_num until multiple_check returns true and returns that number.

This is like P3 in that it's definitely cheating and will have to be re-written with custom logic (even though it will almost certainly be much slower)
