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 4,840,013, 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 | 4,840,013 | |
| -1 | -4,840,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,840,013.
Example:
1 x 4,840,013 = 4,840,013
and
-1 x -4,840,013 = 4,840,013
Notice both answers equal 4,840,013
With that explanation out of the way, let's continue. Next, we take the number 4,840,013 and divide it by 2:
4,840,013 ÷ 2 = 2,420,006.5
If the quotient is a whole number, then 2 and 2,420,006.5 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 | 4,840,013 | |
| -1 | -4,840,013 |
Now, we try dividing 4,840,013 by 3:
4,840,013 ÷ 3 = 1,613,337.6667
If the quotient is a whole number, then 3 and 1,613,337.6667 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 | 4,840,013 | |
| -1 | -4,840,013 |
Let's try dividing by 4:
4,840,013 ÷ 4 = 1,210,003.25
If the quotient is a whole number, then 4 and 1,210,003.25 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 | 4,840,013 | |
| -1 | 4,840,013 |
If you did it right, you will end up with this table:
| 1 | 29 | 47 | 53 | 67 | 1,363 | 1,537 | 1,943 | 2,491 | 3,149 | 3,551 | 72,239 | 91,321 | 102,979 | 166,897 | 4,840,013 |
| -1 | -29 | -47 | -53 | -67 | -1,363 | -1,537 | -1,943 | -2,491 | -3,149 | -3,551 | -72,239 | -91,321 | -102,979 | -166,897 | -4,840,013 |
