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 13,631,569, 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 | 13,631,569 | |
| -1 | -13,631,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,631,569.
Example:
1 x 13,631,569 = 13,631,569
and
-1 x -13,631,569 = 13,631,569
Notice both answers equal 13,631,569
With that explanation out of the way, let's continue. Next, we take the number 13,631,569 and divide it by 2:
13,631,569 ÷ 2 = 6,815,784.5
If the quotient is a whole number, then 2 and 6,815,784.5 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 | 13,631,569 | |
| -1 | -13,631,569 |
Now, we try dividing 13,631,569 by 3:
13,631,569 ÷ 3 = 4,543,856.3333
If the quotient is a whole number, then 3 and 4,543,856.3333 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 | 13,631,569 | |
| -1 | -13,631,569 |
Let's try dividing by 4:
13,631,569 ÷ 4 = 3,407,892.25
If the quotient is a whole number, then 4 and 3,407,892.25 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 | 13,631,569 | |
| -1 | 13,631,569 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 6,029 | 42,203 | 102,493 | 114,551 | 717,451 | 801,857 | 1,947,367 | 13,631,569 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -6,029 | -42,203 | -102,493 | -114,551 | -717,451 | -801,857 | -1,947,367 | -13,631,569 |
