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 11,000,309, 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 | 11,000,309 | |
| -1 | -11,000,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,000,309.
Example:
1 x 11,000,309 = 11,000,309
and
-1 x -11,000,309 = 11,000,309
Notice both answers equal 11,000,309
With that explanation out of the way, let's continue. Next, we take the number 11,000,309 and divide it by 2:
11,000,309 ÷ 2 = 5,500,154.5
If the quotient is a whole number, then 2 and 5,500,154.5 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 | 11,000,309 | |
| -1 | -11,000,309 |
Now, we try dividing 11,000,309 by 3:
11,000,309 ÷ 3 = 3,666,769.6667
If the quotient is a whole number, then 3 and 3,666,769.6667 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 | 11,000,309 | |
| -1 | -11,000,309 |
Let's try dividing by 4:
11,000,309 ÷ 4 = 2,750,077.25
If the quotient is a whole number, then 4 and 2,750,077.25 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 | 11,000,309 | |
| -1 | 11,000,309 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 53 | 421 | 493 | 901 | 1,537 | 7,157 | 12,209 | 22,313 | 26,129 | 207,553 | 379,321 | 647,077 | 11,000,309 |
| -1 | -17 | -29 | -53 | -421 | -493 | -901 | -1,537 | -7,157 | -12,209 | -22,313 | -26,129 | -207,553 | -379,321 | -647,077 | -11,000,309 |
