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 11,071,291, 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 | 11,071,291 | |
| -1 | -11,071,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,071,291.
Example:
1 x 11,071,291 = 11,071,291
and
-1 x -11,071,291 = 11,071,291
Notice both answers equal 11,071,291
With that explanation out of the way, let's continue. Next, we take the number 11,071,291 and divide it by 2:
11,071,291 ÷ 2 = 5,535,645.5
If the quotient is a whole number, then 2 and 5,535,645.5 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 | 11,071,291 | |
| -1 | -11,071,291 |
Now, we try dividing 11,071,291 by 3:
11,071,291 ÷ 3 = 3,690,430.3333
If the quotient is a whole number, then 3 and 3,690,430.3333 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 | 11,071,291 | |
| -1 | -11,071,291 |
Let's try dividing by 4:
11,071,291 ÷ 4 = 2,767,822.75
If the quotient is a whole number, then 4 and 2,767,822.75 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 | 11,071,291 | |
| -1 | 11,071,291 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 59 | 77 | 413 | 649 | 2,437 | 4,543 | 17,059 | 26,807 | 143,783 | 187,649 | 1,006,481 | 1,581,613 | 11,071,291 |
| -1 | -7 | -11 | -59 | -77 | -413 | -649 | -2,437 | -4,543 | -17,059 | -26,807 | -143,783 | -187,649 | -1,006,481 | -1,581,613 | -11,071,291 |
