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 13,055,365, 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 | 13,055,365 | |
| -1 | -13,055,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,055,365.
Example:
1 x 13,055,365 = 13,055,365
and
-1 x -13,055,365 = 13,055,365
Notice both answers equal 13,055,365
With that explanation out of the way, let's continue. Next, we take the number 13,055,365 and divide it by 2:
13,055,365 ÷ 2 = 6,527,682.5
If the quotient is a whole number, then 2 and 6,527,682.5 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 | 13,055,365 | |
| -1 | -13,055,365 |
Now, we try dividing 13,055,365 by 3:
13,055,365 ÷ 3 = 4,351,788.3333
If the quotient is a whole number, then 3 and 4,351,788.3333 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 | 13,055,365 | |
| -1 | -13,055,365 |
Let's try dividing by 4:
13,055,365 ÷ 4 = 3,263,841.25
If the quotient is a whole number, then 4 and 3,263,841.25 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 | 13,055,365 | |
| -1 | 13,055,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 179 | 503 | 895 | 2,515 | 5,191 | 14,587 | 25,955 | 72,935 | 90,037 | 450,185 | 2,611,073 | 13,055,365 |
| -1 | -5 | -29 | -145 | -179 | -503 | -895 | -2,515 | -5,191 | -14,587 | -25,955 | -72,935 | -90,037 | -450,185 | -2,611,073 | -13,055,365 |
