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 10,333,385, 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 | 10,333,385 | |
| -1 | -10,333,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,333,385.
Example:
1 x 10,333,385 = 10,333,385
and
-1 x -10,333,385 = 10,333,385
Notice both answers equal 10,333,385
With that explanation out of the way, let's continue. Next, we take the number 10,333,385 and divide it by 2:
10,333,385 ÷ 2 = 5,166,692.5
If the quotient is a whole number, then 2 and 5,166,692.5 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 | 10,333,385 | |
| -1 | -10,333,385 |
Now, we try dividing 10,333,385 by 3:
10,333,385 ÷ 3 = 3,444,461.6667
If the quotient is a whole number, then 3 and 3,444,461.6667 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 | 10,333,385 | |
| -1 | -10,333,385 |
Let's try dividing by 4:
10,333,385 ÷ 4 = 2,583,346.25
If the quotient is a whole number, then 4 and 2,583,346.25 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 | 10,333,385 | |
| -1 | 10,333,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 163 | 409 | 815 | 2,045 | 5,053 | 12,679 | 25,265 | 63,395 | 66,667 | 333,335 | 2,066,677 | 10,333,385 |
| -1 | -5 | -31 | -155 | -163 | -409 | -815 | -2,045 | -5,053 | -12,679 | -25,265 | -63,395 | -66,667 | -333,335 | -2,066,677 | -10,333,385 |
