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 11,154,871, 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 | 11,154,871 | |
| -1 | -11,154,871 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,154,871.
Example:
1 x 11,154,871 = 11,154,871
and
-1 x -11,154,871 = 11,154,871
Notice both answers equal 11,154,871
With that explanation out of the way, let's continue. Next, we take the number 11,154,871 and divide it by 2:
11,154,871 ÷ 2 = 5,577,435.5
If the quotient is a whole number, then 2 and 5,577,435.5 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 | 11,154,871 | |
| -1 | -11,154,871 |
Now, we try dividing 11,154,871 by 3:
11,154,871 ÷ 3 = 3,718,290.3333
If the quotient is a whole number, then 3 and 3,718,290.3333 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 | 11,154,871 | |
| -1 | -11,154,871 |
Let's try dividing by 4:
11,154,871 ÷ 4 = 2,788,717.75
If the quotient is a whole number, then 4 and 2,788,717.75 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 | 11,154,871 | |
| -1 | 11,154,871 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 91 | 259 | 481 | 3,313 | 3,367 | 23,191 | 43,069 | 122,581 | 301,483 | 858,067 | 1,593,553 | 11,154,871 |
| -1 | -7 | -13 | -37 | -91 | -259 | -481 | -3,313 | -3,367 | -23,191 | -43,069 | -122,581 | -301,483 | -858,067 | -1,593,553 | -11,154,871 |
