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 28,328,575, 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 | 28,328,575 | |
| -1 | -28,328,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,328,575.
Example:
1 x 28,328,575 = 28,328,575
and
-1 x -28,328,575 = 28,328,575
Notice both answers equal 28,328,575
With that explanation out of the way, let's continue. Next, we take the number 28,328,575 and divide it by 2:
28,328,575 ÷ 2 = 14,164,287.5
If the quotient is a whole number, then 2 and 14,164,287.5 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 | 28,328,575 | |
| -1 | -28,328,575 |
Now, we try dividing 28,328,575 by 3:
28,328,575 ÷ 3 = 9,442,858.3333
If the quotient is a whole number, then 3 and 9,442,858.3333 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 | 28,328,575 | |
| -1 | -28,328,575 |
Let's try dividing by 4:
28,328,575 ÷ 4 = 7,082,143.75
If the quotient is a whole number, then 4 and 7,082,143.75 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 | 28,328,575 | |
| -1 | 28,328,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 55 | 155 | 275 | 341 | 775 | 1,705 | 3,323 | 8,525 | 16,615 | 36,553 | 83,075 | 103,013 | 182,765 | 515,065 | 913,825 | 1,133,143 | 2,575,325 | 5,665,715 | 28,328,575 |
| -1 | -5 | -11 | -25 | -31 | -55 | -155 | -275 | -341 | -775 | -1,705 | -3,323 | -8,525 | -16,615 | -36,553 | -83,075 | -103,013 | -182,765 | -515,065 | -913,825 | -1,133,143 | -2,575,325 | -5,665,715 | -28,328,575 |
