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 13,335,127, 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 | 13,335,127 | |
| -1 | -13,335,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,335,127.
Example:
1 x 13,335,127 = 13,335,127
and
-1 x -13,335,127 = 13,335,127
Notice both answers equal 13,335,127
With that explanation out of the way, let's continue. Next, we take the number 13,335,127 and divide it by 2:
13,335,127 ÷ 2 = 6,667,563.5
If the quotient is a whole number, then 2 and 6,667,563.5 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 | 13,335,127 | |
| -1 | -13,335,127 |
Now, we try dividing 13,335,127 by 3:
13,335,127 ÷ 3 = 4,445,042.3333
If the quotient is a whole number, then 3 and 4,445,042.3333 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 | 13,335,127 | |
| -1 | -13,335,127 |
Let's try dividing by 4:
13,335,127 ÷ 4 = 3,333,781.75
If the quotient is a whole number, then 4 and 3,333,781.75 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 | 13,335,127 | |
| -1 | 13,335,127 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 127 | 197 | 533 | 1,651 | 2,561 | 5,207 | 8,077 | 25,019 | 67,691 | 105,001 | 325,247 | 1,025,779 | 13,335,127 |
| -1 | -13 | -41 | -127 | -197 | -533 | -1,651 | -2,561 | -5,207 | -8,077 | -25,019 | -67,691 | -105,001 | -325,247 | -1,025,779 | -13,335,127 |
