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 5,015,521, 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 | 5,015,521 | |
| -1 | -5,015,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,015,521.
Example:
1 x 5,015,521 = 5,015,521
and
-1 x -5,015,521 = 5,015,521
Notice both answers equal 5,015,521
With that explanation out of the way, let's continue. Next, we take the number 5,015,521 and divide it by 2:
5,015,521 ÷ 2 = 2,507,760.5
If the quotient is a whole number, then 2 and 2,507,760.5 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 | 5,015,521 | |
| -1 | -5,015,521 |
Now, we try dividing 5,015,521 by 3:
5,015,521 ÷ 3 = 1,671,840.3333
If the quotient is a whole number, then 3 and 1,671,840.3333 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 | 5,015,521 | |
| -1 | -5,015,521 |
Let's try dividing by 4:
5,015,521 ÷ 4 = 1,253,880.25
If the quotient is a whole number, then 4 and 1,253,880.25 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 | 5,015,521 | |
| -1 | 5,015,521 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 31 | 203 | 217 | 797 | 899 | 5,579 | 6,293 | 23,113 | 24,707 | 161,791 | 172,949 | 716,503 | 5,015,521 |
| -1 | -7 | -29 | -31 | -203 | -217 | -797 | -899 | -5,579 | -6,293 | -23,113 | -24,707 | -161,791 | -172,949 | -716,503 | -5,015,521 |
