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 10,440,311, 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 | 10,440,311 | |
| -1 | -10,440,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,440,311.
Example:
1 x 10,440,311 = 10,440,311
and
-1 x -10,440,311 = 10,440,311
Notice both answers equal 10,440,311
With that explanation out of the way, let's continue. Next, we take the number 10,440,311 and divide it by 2:
10,440,311 ÷ 2 = 5,220,155.5
If the quotient is a whole number, then 2 and 5,220,155.5 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 | 10,440,311 | |
| -1 | -10,440,311 |
Now, we try dividing 10,440,311 by 3:
10,440,311 ÷ 3 = 3,480,103.6667
If the quotient is a whole number, then 3 and 3,480,103.6667 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 | 10,440,311 | |
| -1 | -10,440,311 |
Let's try dividing by 4:
10,440,311 ÷ 4 = 2,610,077.75
If the quotient is a whole number, then 4 and 2,610,077.75 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 | 10,440,311 | |
| -1 | 10,440,311 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 107 | 263 | 371 | 749 | 1,841 | 5,671 | 13,939 | 28,141 | 39,697 | 97,573 | 196,987 | 1,491,473 | 10,440,311 |
| -1 | -7 | -53 | -107 | -263 | -371 | -749 | -1,841 | -5,671 | -13,939 | -28,141 | -39,697 | -97,573 | -196,987 | -1,491,473 | -10,440,311 |
