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 2,442,013, 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 | 2,442,013 | |
| -1 | -2,442,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,442,013.
Example:
1 x 2,442,013 = 2,442,013
and
-1 x -2,442,013 = 2,442,013
Notice both answers equal 2,442,013
With that explanation out of the way, let's continue. Next, we take the number 2,442,013 and divide it by 2:
2,442,013 ÷ 2 = 1,221,006.5
If the quotient is a whole number, then 2 and 1,221,006.5 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 | 2,442,013 | |
| -1 | -2,442,013 |
Now, we try dividing 2,442,013 by 3:
2,442,013 ÷ 3 = 814,004.3333
If the quotient is a whole number, then 3 and 814,004.3333 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 | 2,442,013 | |
| -1 | -2,442,013 |
Let's try dividing by 4:
2,442,013 ÷ 4 = 610,503.25
If the quotient is a whole number, then 4 and 610,503.25 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 | 2,442,013 | |
| -1 | 2,442,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 49 | 61 | 133 | 301 | 427 | 817 | 931 | 1,159 | 2,107 | 2,623 | 2,989 | 5,719 | 8,113 | 18,361 | 40,033 | 49,837 | 56,791 | 128,527 | 348,859 | 2,442,013 |
| -1 | -7 | -19 | -43 | -49 | -61 | -133 | -301 | -427 | -817 | -931 | -1,159 | -2,107 | -2,623 | -2,989 | -5,719 | -8,113 | -18,361 | -40,033 | -49,837 | -56,791 | -128,527 | -348,859 | -2,442,013 |
