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 3,094,637, 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 | 3,094,637 | |
| -1 | -3,094,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,094,637.
Example:
1 x 3,094,637 = 3,094,637
and
-1 x -3,094,637 = 3,094,637
Notice both answers equal 3,094,637
With that explanation out of the way, let's continue. Next, we take the number 3,094,637 and divide it by 2:
3,094,637 ÷ 2 = 1,547,318.5
If the quotient is a whole number, then 2 and 1,547,318.5 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 | 3,094,637 | |
| -1 | -3,094,637 |
Now, we try dividing 3,094,637 by 3:
3,094,637 ÷ 3 = 1,031,545.6667
If the quotient is a whole number, then 3 and 1,031,545.6667 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 | 3,094,637 | |
| -1 | -3,094,637 |
Let's try dividing by 4:
3,094,637 ÷ 4 = 773,659.25
If the quotient is a whole number, then 4 and 773,659.25 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 | 3,094,637 | |
| -1 | 3,094,637 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 1,097 | 2,821 | 7,679 | 14,261 | 34,007 | 99,827 | 238,049 | 442,091 | 3,094,637 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -1,097 | -2,821 | -7,679 | -14,261 | -34,007 | -99,827 | -238,049 | -442,091 | -3,094,637 |
