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 10,553,785, 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 | 10,553,785 | |
| -1 | -10,553,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,553,785.
Example:
1 x 10,553,785 = 10,553,785
and
-1 x -10,553,785 = 10,553,785
Notice both answers equal 10,553,785
With that explanation out of the way, let's continue. Next, we take the number 10,553,785 and divide it by 2:
10,553,785 ÷ 2 = 5,276,892.5
If the quotient is a whole number, then 2 and 5,276,892.5 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 | 10,553,785 | |
| -1 | -10,553,785 |
Now, we try dividing 10,553,785 by 3:
10,553,785 ÷ 3 = 3,517,928.3333
If the quotient is a whole number, then 3 and 3,517,928.3333 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 | 10,553,785 | |
| -1 | -10,553,785 |
Let's try dividing by 4:
10,553,785 ÷ 4 = 2,638,446.25
If the quotient is a whole number, then 4 and 2,638,446.25 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 | 10,553,785 | |
| -1 | 10,553,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 311 | 617 | 1,555 | 3,085 | 3,421 | 6,787 | 17,105 | 33,935 | 191,887 | 959,435 | 2,110,757 | 10,553,785 |
| -1 | -5 | -11 | -55 | -311 | -617 | -1,555 | -3,085 | -3,421 | -6,787 | -17,105 | -33,935 | -191,887 | -959,435 | -2,110,757 | -10,553,785 |
