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 13,066,501, 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 | 13,066,501 | |
| -1 | -13,066,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,066,501.
Example:
1 x 13,066,501 = 13,066,501
and
-1 x -13,066,501 = 13,066,501
Notice both answers equal 13,066,501
With that explanation out of the way, let's continue. Next, we take the number 13,066,501 and divide it by 2:
13,066,501 ÷ 2 = 6,533,250.5
If the quotient is a whole number, then 2 and 6,533,250.5 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 | 13,066,501 | |
| -1 | -13,066,501 |
Now, we try dividing 13,066,501 by 3:
13,066,501 ÷ 3 = 4,355,500.3333
If the quotient is a whole number, then 3 and 4,355,500.3333 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 | 13,066,501 | |
| -1 | -13,066,501 |
Let's try dividing by 4:
13,066,501 ÷ 4 = 3,266,625.25
If the quotient is a whole number, then 4 and 3,266,625.25 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 | 13,066,501 | |
| -1 | 13,066,501 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 191 | 203 | 337 | 1,337 | 2,359 | 5,539 | 9,773 | 38,773 | 64,367 | 68,411 | 450,569 | 1,866,643 | 13,066,501 |
| -1 | -7 | -29 | -191 | -203 | -337 | -1,337 | -2,359 | -5,539 | -9,773 | -38,773 | -64,367 | -68,411 | -450,569 | -1,866,643 | -13,066,501 |
