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 3,029,845, 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 | 3,029,845 | |
| -1 | -3,029,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,029,845.
Example:
1 x 3,029,845 = 3,029,845
and
-1 x -3,029,845 = 3,029,845
Notice both answers equal 3,029,845
With that explanation out of the way, let's continue. Next, we take the number 3,029,845 and divide it by 2:
3,029,845 ÷ 2 = 1,514,922.5
If the quotient is a whole number, then 2 and 1,514,922.5 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 | 3,029,845 | |
| -1 | -3,029,845 |
Now, we try dividing 3,029,845 by 3:
3,029,845 ÷ 3 = 1,009,948.3333
If the quotient is a whole number, then 3 and 1,009,948.3333 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 | 3,029,845 | |
| -1 | -3,029,845 |
Let's try dividing by 4:
3,029,845 ÷ 4 = 757,461.25
If the quotient is a whole number, then 4 and 757,461.25 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 | 3,029,845 | |
| -1 | 3,029,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 6,659 | 33,295 | 46,613 | 86,567 | 233,065 | 432,835 | 605,969 | 3,029,845 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -6,659 | -33,295 | -46,613 | -86,567 | -233,065 | -432,835 | -605,969 | -3,029,845 |
