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 23,143,273, 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 | 23,143,273 | |
| -1 | -23,143,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,143,273.
Example:
1 x 23,143,273 = 23,143,273
and
-1 x -23,143,273 = 23,143,273
Notice both answers equal 23,143,273
With that explanation out of the way, let's continue. Next, we take the number 23,143,273 and divide it by 2:
23,143,273 ÷ 2 = 11,571,636.5
If the quotient is a whole number, then 2 and 11,571,636.5 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 | 23,143,273 | |
| -1 | -23,143,273 |
Now, we try dividing 23,143,273 by 3:
23,143,273 ÷ 3 = 7,714,424.3333
If the quotient is a whole number, then 3 and 7,714,424.3333 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 | 23,143,273 | |
| -1 | -23,143,273 |
Let's try dividing by 4:
23,143,273 ÷ 4 = 5,785,818.25
If the quotient is a whole number, then 4 and 5,785,818.25 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 | 23,143,273 | |
| -1 | 23,143,273 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 137 | 323 | 523 | 2,329 | 2,603 | 8,891 | 9,937 | 44,251 | 71,651 | 168,929 | 1,218,067 | 1,361,369 | 23,143,273 |
| -1 | -17 | -19 | -137 | -323 | -523 | -2,329 | -2,603 | -8,891 | -9,937 | -44,251 | -71,651 | -168,929 | -1,218,067 | -1,361,369 | -23,143,273 |
