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 21,441,469, 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 | 21,441,469 | |
| -1 | -21,441,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,441,469.
Example:
1 x 21,441,469 = 21,441,469
and
-1 x -21,441,469 = 21,441,469
Notice both answers equal 21,441,469
With that explanation out of the way, let's continue. Next, we take the number 21,441,469 and divide it by 2:
21,441,469 ÷ 2 = 10,720,734.5
If the quotient is a whole number, then 2 and 10,720,734.5 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 | 21,441,469 | |
| -1 | -21,441,469 |
Now, we try dividing 21,441,469 by 3:
21,441,469 ÷ 3 = 7,147,156.3333
If the quotient is a whole number, then 3 and 7,147,156.3333 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 | 21,441,469 | |
| -1 | -21,441,469 |
Let's try dividing by 4:
21,441,469 ÷ 4 = 5,360,367.25
If the quotient is a whole number, then 4 and 5,360,367.25 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 | 21,441,469 | |
| -1 | 21,441,469 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 79 | 191 | 203 | 553 | 1,337 | 1,421 | 2,291 | 3,871 | 5,539 | 9,359 | 15,089 | 16,037 | 38,773 | 105,623 | 112,259 | 271,411 | 437,581 | 739,361 | 3,063,067 | 21,441,469 |
| -1 | -7 | -29 | -49 | -79 | -191 | -203 | -553 | -1,337 | -1,421 | -2,291 | -3,871 | -5,539 | -9,359 | -15,089 | -16,037 | -38,773 | -105,623 | -112,259 | -271,411 | -437,581 | -739,361 | -3,063,067 | -21,441,469 |
