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 11,089,381, 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 | 11,089,381 | |
| -1 | -11,089,381 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,089,381.
Example:
1 x 11,089,381 = 11,089,381
and
-1 x -11,089,381 = 11,089,381
Notice both answers equal 11,089,381
With that explanation out of the way, let's continue. Next, we take the number 11,089,381 and divide it by 2:
11,089,381 ÷ 2 = 5,544,690.5
If the quotient is a whole number, then 2 and 5,544,690.5 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 | 11,089,381 | |
| -1 | -11,089,381 |
Now, we try dividing 11,089,381 by 3:
11,089,381 ÷ 3 = 3,696,460.3333
If the quotient is a whole number, then 3 and 3,696,460.3333 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 | 11,089,381 | |
| -1 | -11,089,381 |
Let's try dividing by 4:
11,089,381 ÷ 4 = 2,772,345.25
If the quotient is a whole number, then 4 and 2,772,345.25 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 | 11,089,381 | |
| -1 | 11,089,381 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 83 | 157 | 851 | 1,909 | 3,071 | 3,611 | 5,809 | 13,031 | 70,633 | 133,607 | 299,713 | 482,147 | 11,089,381 |
| -1 | -23 | -37 | -83 | -157 | -851 | -1,909 | -3,071 | -3,611 | -5,809 | -13,031 | -70,633 | -133,607 | -299,713 | -482,147 | -11,089,381 |
