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 1,145,885, 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 | 1,145,885 | |
| -1 | -1,145,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,145,885.
Example:
1 x 1,145,885 = 1,145,885
and
-1 x -1,145,885 = 1,145,885
Notice both answers equal 1,145,885
With that explanation out of the way, let's continue. Next, we take the number 1,145,885 and divide it by 2:
1,145,885 ÷ 2 = 572,942.5
If the quotient is a whole number, then 2 and 572,942.5 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 | 1,145,885 | |
| -1 | -1,145,885 |
Now, we try dividing 1,145,885 by 3:
1,145,885 ÷ 3 = 381,961.6667
If the quotient is a whole number, then 3 and 381,961.6667 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 | 1,145,885 | |
| -1 | -1,145,885 |
Let's try dividing by 4:
1,145,885 ÷ 4 = 286,471.25
If the quotient is a whole number, then 4 and 286,471.25 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 | 1,145,885 | |
| -1 | 1,145,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 61 | 65 | 85 | 221 | 289 | 305 | 793 | 1,037 | 1,105 | 1,445 | 3,757 | 3,965 | 5,185 | 13,481 | 17,629 | 18,785 | 67,405 | 88,145 | 229,177 | 1,145,885 |
| -1 | -5 | -13 | -17 | -61 | -65 | -85 | -221 | -289 | -305 | -793 | -1,037 | -1,105 | -1,445 | -3,757 | -3,965 | -5,185 | -13,481 | -17,629 | -18,785 | -67,405 | -88,145 | -229,177 | -1,145,885 |
