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 10,553,515, 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 | 10,553,515 | |
| -1 | -10,553,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,553,515.
Example:
1 x 10,553,515 = 10,553,515
and
-1 x -10,553,515 = 10,553,515
Notice both answers equal 10,553,515
With that explanation out of the way, let's continue. Next, we take the number 10,553,515 and divide it by 2:
10,553,515 ÷ 2 = 5,276,757.5
If the quotient is a whole number, then 2 and 5,276,757.5 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 | 10,553,515 | |
| -1 | -10,553,515 |
Now, we try dividing 10,553,515 by 3:
10,553,515 ÷ 3 = 3,517,838.3333
If the quotient is a whole number, then 3 and 3,517,838.3333 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 | 10,553,515 | |
| -1 | -10,553,515 |
Let's try dividing by 4:
10,553,515 ÷ 4 = 2,638,378.75
If the quotient is a whole number, then 4 and 2,638,378.75 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 | 10,553,515 | |
| -1 | 10,553,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 17,737 | 88,685 | 124,159 | 301,529 | 620,795 | 1,507,645 | 2,110,703 | 10,553,515 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -17,737 | -88,685 | -124,159 | -301,529 | -620,795 | -1,507,645 | -2,110,703 | -10,553,515 |
