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 3,004,145, 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 | 3,004,145 | |
| -1 | -3,004,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,004,145.
Example:
1 x 3,004,145 = 3,004,145
and
-1 x -3,004,145 = 3,004,145
Notice both answers equal 3,004,145
With that explanation out of the way, let's continue. Next, we take the number 3,004,145 and divide it by 2:
3,004,145 ÷ 2 = 1,502,072.5
If the quotient is a whole number, then 2 and 1,502,072.5 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 | 3,004,145 | |
| -1 | -3,004,145 |
Now, we try dividing 3,004,145 by 3:
3,004,145 ÷ 3 = 1,001,381.6667
If the quotient is a whole number, then 3 and 1,001,381.6667 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 | 3,004,145 | |
| -1 | -3,004,145 |
Let's try dividing by 4:
3,004,145 ÷ 4 = 751,036.25
If the quotient is a whole number, then 4 and 751,036.25 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 | 3,004,145 | |
| -1 | 3,004,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 151 | 173 | 755 | 865 | 3,473 | 3,979 | 17,365 | 19,895 | 26,123 | 130,615 | 600,829 | 3,004,145 |
| -1 | -5 | -23 | -115 | -151 | -173 | -755 | -865 | -3,473 | -3,979 | -17,365 | -19,895 | -26,123 | -130,615 | -600,829 | -3,004,145 |
