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 14,553,221, 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 | 14,553,221 | |
| -1 | -14,553,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,553,221.
Example:
1 x 14,553,221 = 14,553,221
and
-1 x -14,553,221 = 14,553,221
Notice both answers equal 14,553,221
With that explanation out of the way, let's continue. Next, we take the number 14,553,221 and divide it by 2:
14,553,221 ÷ 2 = 7,276,610.5
If the quotient is a whole number, then 2 and 7,276,610.5 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 | 14,553,221 | |
| -1 | -14,553,221 |
Now, we try dividing 14,553,221 by 3:
14,553,221 ÷ 3 = 4,851,073.6667
If the quotient is a whole number, then 3 and 4,851,073.6667 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 | 14,553,221 | |
| -1 | -14,553,221 |
Let's try dividing by 4:
14,553,221 ÷ 4 = 3,638,305.25
If the quotient is a whole number, then 4 and 3,638,305.25 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 | 14,553,221 | |
| -1 | 14,553,221 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 47 | 379 | 817 | 893 | 2,021 | 7,201 | 16,297 | 17,813 | 38,399 | 309,643 | 338,447 | 765,959 | 14,553,221 |
| -1 | -19 | -43 | -47 | -379 | -817 | -893 | -2,021 | -7,201 | -16,297 | -17,813 | -38,399 | -309,643 | -338,447 | -765,959 | -14,553,221 |
