This simple calculator allows you to compute the Highest Common Factor (or Greatest Common Divisor) for up to six numbers.

*Instructions*

Just enter the numbers for which you wish to calculate the Highest Common Factor into the boxes below, and then hit the calculate button.

A couple of things to bear in mind. First, the numbers must be integers. Second, the numbers must be entered into consecutive boxes (for example, if you've got five numbers, then use boxes 1 to 5).

Please specify at least two numbers for which you wish to calculate the
Highest Common Factor).
