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 13,017,229, 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 | 13,017,229 | |
| -1 | -13,017,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,017,229.
Example:
1 x 13,017,229 = 13,017,229
and
-1 x -13,017,229 = 13,017,229
Notice both answers equal 13,017,229
With that explanation out of the way, let's continue. Next, we take the number 13,017,229 and divide it by 2:
13,017,229 ÷ 2 = 6,508,614.5
If the quotient is a whole number, then 2 and 6,508,614.5 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 | 13,017,229 | |
| -1 | -13,017,229 |
Now, we try dividing 13,017,229 by 3:
13,017,229 ÷ 3 = 4,339,076.3333
If the quotient is a whole number, then 3 and 4,339,076.3333 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 | 13,017,229 | |
| -1 | -13,017,229 |
Let's try dividing by 4:
13,017,229 ÷ 4 = 3,254,307.25
If the quotient is a whole number, then 4 and 3,254,307.25 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 | 13,017,229 | |
| -1 | 13,017,229 |
If you did it right, you will end up with this table:
| 1 | 37 | 59 | 67 | 89 | 2,183 | 2,479 | 3,293 | 3,953 | 5,251 | 5,963 | 146,261 | 194,287 | 220,631 | 351,817 | 13,017,229 |
| -1 | -37 | -59 | -67 | -89 | -2,183 | -2,479 | -3,293 | -3,953 | -5,251 | -5,963 | -146,261 | -194,287 | -220,631 | -351,817 | -13,017,229 |
