Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 503,125, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 503,125 | |
| -1 | -503,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 503,125.
Example:
1 x 503,125 = 503,125
and
-1 x -503,125 = 503,125
Notice both answers equal 503,125
With that explanation out of the way, let's continue. Next, we take the number 503,125 and divide it by 2:
503,125 ÷ 2 = 251,562.5
If the quotient is a whole number, then 2 and 251,562.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 503,125 | |
| -1 | -503,125 |
Now, we try dividing 503,125 by 3:
503,125 ÷ 3 = 167,708.3333
If the quotient is a whole number, then 3 and 167,708.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 503,125 | |
| -1 | -503,125 |
Let's try dividing by 4:
503,125 ÷ 4 = 125,781.25
If the quotient is a whole number, then 4 and 125,781.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 503,125 | |
| -1 | 503,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 25 | 35 | 115 | 125 | 161 | 175 | 575 | 625 | 805 | 875 | 2,875 | 3,125 | 4,025 | 4,375 | 14,375 | 20,125 | 21,875 | 71,875 | 100,625 | 503,125 |
| -1 | -5 | -7 | -23 | -25 | -35 | -115 | -125 | -161 | -175 | -575 | -625 | -805 | -875 | -2,875 | -3,125 | -4,025 | -4,375 | -14,375 | -20,125 | -21,875 | -71,875 | -100,625 | -503,125 |
