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 11,275,159, 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 | 11,275,159 | |
| -1 | -11,275,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,275,159.
Example:
1 x 11,275,159 = 11,275,159
and
-1 x -11,275,159 = 11,275,159
Notice both answers equal 11,275,159
With that explanation out of the way, let's continue. Next, we take the number 11,275,159 and divide it by 2:
11,275,159 ÷ 2 = 5,637,579.5
If the quotient is a whole number, then 2 and 5,637,579.5 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 | 11,275,159 | |
| -1 | -11,275,159 |
Now, we try dividing 11,275,159 by 3:
11,275,159 ÷ 3 = 3,758,386.3333
If the quotient is a whole number, then 3 and 3,758,386.3333 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 | 11,275,159 | |
| -1 | -11,275,159 |
Let's try dividing by 4:
11,275,159 ÷ 4 = 2,818,789.75
If the quotient is a whole number, then 4 and 2,818,789.75 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 | 11,275,159 | |
| -1 | 11,275,159 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 47 | 301 | 329 | 797 | 2,021 | 5,579 | 14,147 | 34,271 | 37,459 | 239,897 | 262,213 | 1,610,737 | 11,275,159 |
| -1 | -7 | -43 | -47 | -301 | -329 | -797 | -2,021 | -5,579 | -14,147 | -34,271 | -37,459 | -239,897 | -262,213 | -1,610,737 | -11,275,159 |
