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 28,367,573, 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 | 28,367,573 | |
| -1 | -28,367,573 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,367,573.
Example:
1 x 28,367,573 = 28,367,573
and
-1 x -28,367,573 = 28,367,573
Notice both answers equal 28,367,573
With that explanation out of the way, let's continue. Next, we take the number 28,367,573 and divide it by 2:
28,367,573 ÷ 2 = 14,183,786.5
If the quotient is a whole number, then 2 and 14,183,786.5 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 | 28,367,573 | |
| -1 | -28,367,573 |
Now, we try dividing 28,367,573 by 3:
28,367,573 ÷ 3 = 9,455,857.6667
If the quotient is a whole number, then 3 and 9,455,857.6667 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 | 28,367,573 | |
| -1 | -28,367,573 |
Let's try dividing by 4:
28,367,573 ÷ 4 = 7,091,893.25
If the quotient is a whole number, then 4 and 7,091,893.25 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 | 28,367,573 | |
| -1 | 28,367,573 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 43 | 403 | 559 | 1,333 | 1,637 | 17,329 | 21,281 | 50,747 | 70,391 | 659,711 | 915,083 | 2,182,121 | 28,367,573 |
| -1 | -13 | -31 | -43 | -403 | -559 | -1,333 | -1,637 | -17,329 | -21,281 | -50,747 | -70,391 | -659,711 | -915,083 | -2,182,121 | -28,367,573 |
