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 13,314,133, 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 | 13,314,133 | |
| -1 | -13,314,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,314,133.
Example:
1 x 13,314,133 = 13,314,133
and
-1 x -13,314,133 = 13,314,133
Notice both answers equal 13,314,133
With that explanation out of the way, let's continue. Next, we take the number 13,314,133 and divide it by 2:
13,314,133 ÷ 2 = 6,657,066.5
If the quotient is a whole number, then 2 and 6,657,066.5 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 | 13,314,133 | |
| -1 | -13,314,133 |
Now, we try dividing 13,314,133 by 3:
13,314,133 ÷ 3 = 4,438,044.3333
If the quotient is a whole number, then 3 and 4,438,044.3333 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 | 13,314,133 | |
| -1 | -13,314,133 |
Let's try dividing by 4:
13,314,133 ÷ 4 = 3,328,533.25
If the quotient is a whole number, then 4 and 3,328,533.25 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 | 13,314,133 | |
| -1 | 13,314,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 49 | 71 | 89 | 301 | 497 | 623 | 2,107 | 3,053 | 3,479 | 3,827 | 4,361 | 6,319 | 21,371 | 26,789 | 44,233 | 149,597 | 187,523 | 271,717 | 309,631 | 1,902,019 | 13,314,133 |
| -1 | -7 | -43 | -49 | -71 | -89 | -301 | -497 | -623 | -2,107 | -3,053 | -3,479 | -3,827 | -4,361 | -6,319 | -21,371 | -26,789 | -44,233 | -149,597 | -187,523 | -271,717 | -309,631 | -1,902,019 | -13,314,133 |
