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 28,452,593, 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 | 28,452,593 | |
| -1 | -28,452,593 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,452,593.
Example:
1 x 28,452,593 = 28,452,593
and
-1 x -28,452,593 = 28,452,593
Notice both answers equal 28,452,593
With that explanation out of the way, let's continue. Next, we take the number 28,452,593 and divide it by 2:
28,452,593 ÷ 2 = 14,226,296.5
If the quotient is a whole number, then 2 and 14,226,296.5 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 | 28,452,593 | |
| -1 | -28,452,593 |
Now, we try dividing 28,452,593 by 3:
28,452,593 ÷ 3 = 9,484,197.6667
If the quotient is a whole number, then 3 and 9,484,197.6667 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 | 28,452,593 | |
| -1 | -28,452,593 |
Let's try dividing by 4:
28,452,593 ÷ 4 = 7,113,148.25
If the quotient is a whole number, then 4 and 7,113,148.25 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 | 28,452,593 | |
| -1 | 28,452,593 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 149 | 397 | 481 | 1,937 | 5,161 | 5,513 | 14,689 | 59,153 | 71,669 | 190,957 | 768,989 | 2,188,661 | 28,452,593 |
| -1 | -13 | -37 | -149 | -397 | -481 | -1,937 | -5,161 | -5,513 | -14,689 | -59,153 | -71,669 | -190,957 | -768,989 | -2,188,661 | -28,452,593 |
