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 1,143,125, 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 | 1,143,125 | |
| -1 | -1,143,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,143,125.
Example:
1 x 1,143,125 = 1,143,125
and
-1 x -1,143,125 = 1,143,125
Notice both answers equal 1,143,125
With that explanation out of the way, let's continue. Next, we take the number 1,143,125 and divide it by 2:
1,143,125 ÷ 2 = 571,562.5
If the quotient is a whole number, then 2 and 571,562.5 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 | 1,143,125 | |
| -1 | -1,143,125 |
Now, we try dividing 1,143,125 by 3:
1,143,125 ÷ 3 = 381,041.6667
If the quotient is a whole number, then 3 and 381,041.6667 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 | 1,143,125 | |
| -1 | -1,143,125 |
Let's try dividing by 4:
1,143,125 ÷ 4 = 285,781.25
If the quotient is a whole number, then 4 and 285,781.25 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 | 1,143,125 | |
| -1 | 1,143,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 59 | 125 | 155 | 295 | 625 | 775 | 1,475 | 1,829 | 3,875 | 7,375 | 9,145 | 19,375 | 36,875 | 45,725 | 228,625 | 1,143,125 |
| -1 | -5 | -25 | -31 | -59 | -125 | -155 | -295 | -625 | -775 | -1,475 | -1,829 | -3,875 | -7,375 | -9,145 | -19,375 | -36,875 | -45,725 | -228,625 | -1,143,125 |
