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 4,786,985, 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 | 4,786,985 | |
| -1 | -4,786,985 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,786,985.
Example:
1 x 4,786,985 = 4,786,985
and
-1 x -4,786,985 = 4,786,985
Notice both answers equal 4,786,985
With that explanation out of the way, let's continue. Next, we take the number 4,786,985 and divide it by 2:
4,786,985 ÷ 2 = 2,393,492.5
If the quotient is a whole number, then 2 and 2,393,492.5 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 | 4,786,985 | |
| -1 | -4,786,985 |
Now, we try dividing 4,786,985 by 3:
4,786,985 ÷ 3 = 1,595,661.6667
If the quotient is a whole number, then 3 and 1,595,661.6667 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 | 4,786,985 | |
| -1 | -4,786,985 |
Let's try dividing by 4:
4,786,985 ÷ 4 = 1,196,746.25
If the quotient is a whole number, then 4 and 1,196,746.25 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 | 4,786,985 | |
| -1 | 4,786,985 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 233 | 587 | 1,165 | 1,631 | 2,935 | 4,109 | 8,155 | 20,545 | 136,771 | 683,855 | 957,397 | 4,786,985 |
| -1 | -5 | -7 | -35 | -233 | -587 | -1,165 | -1,631 | -2,935 | -4,109 | -8,155 | -20,545 | -136,771 | -683,855 | -957,397 | -4,786,985 |
