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 8,845,385, 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 | 8,845,385 | |
| -1 | -8,845,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,845,385.
Example:
1 x 8,845,385 = 8,845,385
and
-1 x -8,845,385 = 8,845,385
Notice both answers equal 8,845,385
With that explanation out of the way, let's continue. Next, we take the number 8,845,385 and divide it by 2:
8,845,385 ÷ 2 = 4,422,692.5
If the quotient is a whole number, then 2 and 4,422,692.5 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 | 8,845,385 | |
| -1 | -8,845,385 |
Now, we try dividing 8,845,385 by 3:
8,845,385 ÷ 3 = 2,948,461.6667
If the quotient is a whole number, then 3 and 2,948,461.6667 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 | 8,845,385 | |
| -1 | -8,845,385 |
Let's try dividing by 4:
8,845,385 ÷ 4 = 2,211,346.25
If the quotient is a whole number, then 4 and 2,211,346.25 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 | 8,845,385 | |
| -1 | 8,845,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 149 | 155 | 383 | 745 | 1,915 | 4,619 | 11,873 | 23,095 | 57,067 | 59,365 | 285,335 | 1,769,077 | 8,845,385 |
| -1 | -5 | -31 | -149 | -155 | -383 | -745 | -1,915 | -4,619 | -11,873 | -23,095 | -57,067 | -59,365 | -285,335 | -1,769,077 | -8,845,385 |
