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 28,184,035, 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 | 28,184,035 | |
| -1 | -28,184,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,184,035.
Example:
1 x 28,184,035 = 28,184,035
and
-1 x -28,184,035 = 28,184,035
Notice both answers equal 28,184,035
With that explanation out of the way, let's continue. Next, we take the number 28,184,035 and divide it by 2:
28,184,035 ÷ 2 = 14,092,017.5
If the quotient is a whole number, then 2 and 14,092,017.5 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 | 28,184,035 | |
| -1 | -28,184,035 |
Now, we try dividing 28,184,035 by 3:
28,184,035 ÷ 3 = 9,394,678.3333
If the quotient is a whole number, then 3 and 9,394,678.3333 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 | 28,184,035 | |
| -1 | -28,184,035 |
Let's try dividing by 4:
28,184,035 ÷ 4 = 7,046,008.75
If the quotient is a whole number, then 4 and 7,046,008.75 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 | 28,184,035 | |
| -1 | 28,184,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 419 | 1,223 | 2,095 | 4,609 | 6,115 | 13,453 | 23,045 | 67,265 | 512,437 | 2,562,185 | 5,636,807 | 28,184,035 |
| -1 | -5 | -11 | -55 | -419 | -1,223 | -2,095 | -4,609 | -6,115 | -13,453 | -23,045 | -67,265 | -512,437 | -2,562,185 | -5,636,807 | -28,184,035 |
