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 13,474,243, 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 | 13,474,243 | |
| -1 | -13,474,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,474,243.
Example:
1 x 13,474,243 = 13,474,243
and
-1 x -13,474,243 = 13,474,243
Notice both answers equal 13,474,243
With that explanation out of the way, let's continue. Next, we take the number 13,474,243 and divide it by 2:
13,474,243 ÷ 2 = 6,737,121.5
If the quotient is a whole number, then 2 and 6,737,121.5 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 | 13,474,243 | |
| -1 | -13,474,243 |
Now, we try dividing 13,474,243 by 3:
13,474,243 ÷ 3 = 4,491,414.3333
If the quotient is a whole number, then 3 and 4,491,414.3333 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 | 13,474,243 | |
| -1 | -13,474,243 |
Let's try dividing by 4:
13,474,243 ÷ 4 = 3,368,560.75
If the quotient is a whole number, then 4 and 3,368,560.75 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 | 13,474,243 | |
| -1 | 13,474,243 |
If you did it right, you will end up with this table:
| 1 | 31 | 53 | 59 | 139 | 1,643 | 1,829 | 3,127 | 4,309 | 7,367 | 8,201 | 96,937 | 228,377 | 254,231 | 434,653 | 13,474,243 |
| -1 | -31 | -53 | -59 | -139 | -1,643 | -1,829 | -3,127 | -4,309 | -7,367 | -8,201 | -96,937 | -228,377 | -254,231 | -434,653 | -13,474,243 |
