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 23,305,183, 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 | 23,305,183 | |
| -1 | -23,305,183 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,305,183.
Example:
1 x 23,305,183 = 23,305,183
and
-1 x -23,305,183 = 23,305,183
Notice both answers equal 23,305,183
With that explanation out of the way, let's continue. Next, we take the number 23,305,183 and divide it by 2:
23,305,183 ÷ 2 = 11,652,591.5
If the quotient is a whole number, then 2 and 11,652,591.5 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 | 23,305,183 | |
| -1 | -23,305,183 |
Now, we try dividing 23,305,183 by 3:
23,305,183 ÷ 3 = 7,768,394.3333
If the quotient is a whole number, then 3 and 7,768,394.3333 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 | 23,305,183 | |
| -1 | -23,305,183 |
Let's try dividing by 4:
23,305,183 ÷ 4 = 5,826,295.75
If the quotient is a whole number, then 4 and 5,826,295.75 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 | 23,305,183 | |
| -1 | 23,305,183 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 43 | 319 | 473 | 1,247 | 1,699 | 13,717 | 18,689 | 49,271 | 73,057 | 541,981 | 803,627 | 2,118,653 | 23,305,183 |
| -1 | -11 | -29 | -43 | -319 | -473 | -1,247 | -1,699 | -13,717 | -18,689 | -49,271 | -73,057 | -541,981 | -803,627 | -2,118,653 | -23,305,183 |
