A Flow Chart for Finding Prime Numbers |
Description |
Prime numbers are positive integers that can only be divided evenly by 1 or
themselves. By definition, negative integers, 0, and 1 are not considered prime
numbers. The list of the first few prime numbers looks like: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, ... For example, 5 is a prime number because you can divide 5 by 1 evenly and
divide 5 by 5 without a remainder, but if you divide 5 by any other integer, you
get a remainder. |
Drawing Instructions | If you haven't already done so, first download the
free trial version of RFFlow. It will allow you to open any chart and make
modifications. Once RFFlow is installed, you can open the above charts in RFFlow. Click on prime-numbers.flo for the top flow chart or finding-prime-numbers.flo for the bottom flow chart. From there you can zoom in, edit, and print these sample charts. It is often easier to modify an existing chart than to draw it from scratch. To draw this flow chart without downloading it, run RFFlow, click on the More Shapes button , scroll and open the Flowcharting folder, click the Physical Flowcharting stencil and click the Add Stencil button. |
