### How do I get all the factors of a constant using my calculator?

There is a program on page 253 of the manual (http://support.casio.com/manualfile.php?rgn=5&cid=004002013) to get the prime factors of any number. You could modify the program to get all the factors.

Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example:

120 /1 = 120 thus factor is (1, 120)
120/2 = 60 thus factor is (2, 60)
120/3 = 40 thus factor is (3, 40)
120/4 = 30 thus factor is (4, 30)
120/5 = 24 thus factor is (5, 24)
120/6 = 20 thus factor is (6, 20)
120/7 = 1.7 thus 7 not a factor
120/8 = 15 thus factor is (8,15)
120/9 = 13.3 thus 9 is not a factor
120/10 = 12 thus factor is (10,12)
120/11 = 10.9 thus 11 is not a factor.

Good luck.

### Inverter problem

If you got the store bought APC 350 UPS, you most likely overloaded them, and killed them beyound repair.

People should never buy a 350VA. They are way to small for power supplies most of us now have. you need to start out to 1000VA plus you need to do the math to figure out how big of a UPS you actually need in the show room.
What am I talking about? What is the significant, or the math of what I am saying here. 115V x 1 amps = 115VA x .778 power factor = 89.47 watts Start up 50 watts = 39.47 watts

115V x 9 amps = 1035VA x .778 power factor = 805.23 watts Start up 50 watts = 755.23 watts
115V x 10 amps = 1150VA x .778 power factor = 894.70 watts Start up 50 watts = 844.70 watts
115V x 11 amps = 1265VA x .778 power factor = 984.17 watts Start up 50 watts = 934.17 watts
115V x 12 amps = 1380VA x .778 power factor = 1073.63 watts Start up 50 watts = 1023.63 watts
115V x 13 amps = 1495VA x .778 power factor = 1163.11 watts Start up 50 watts = 1113.11 watts
115V x 14 amps = 1610VA x .778 power factor = 1252.58 watts Start up 50 watts = 1202.58 watts

115V x 17 amps = 1955VA x .778 power factor = 1520.99 watts Start up 50 watts = 1470.99 watts
115V x 18 amps = 2070VA x .778 power factor = 1610.46 watts Start up 50 watts = 1560.46 watts
115V x 19 amps = 2185VA x .778 power factor = 1699.93 watts Start up 50 watts = 1649.93 watts
115V x 20 amps = 2300VA x .778 power factor = 1789.40 watts Start up 50 watts = 1739.40 watts
