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 5,012,501, 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 | 5,012,501 | |
| -1 | -5,012,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,012,501.
Example:
1 x 5,012,501 = 5,012,501
and
-1 x -5,012,501 = 5,012,501
Notice both answers equal 5,012,501
With that explanation out of the way, let's continue. Next, we take the number 5,012,501 and divide it by 2:
5,012,501 ÷ 2 = 2,506,250.5
If the quotient is a whole number, then 2 and 2,506,250.5 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 | 5,012,501 | |
| -1 | -5,012,501 |
Now, we try dividing 5,012,501 by 3:
5,012,501 ÷ 3 = 1,670,833.6667
If the quotient is a whole number, then 3 and 1,670,833.6667 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 | 5,012,501 | |
| -1 | -5,012,501 |
Let's try dividing by 4:
5,012,501 ÷ 4 = 1,253,125.25
If the quotient is a whole number, then 4 and 1,253,125.25 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 | 5,012,501 | |
| -1 | 5,012,501 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 37 | 221 | 481 | 613 | 629 | 7,969 | 8,177 | 10,421 | 22,681 | 135,473 | 294,853 | 385,577 | 5,012,501 |
| -1 | -13 | -17 | -37 | -221 | -481 | -613 | -629 | -7,969 | -8,177 | -10,421 | -22,681 | -135,473 | -294,853 | -385,577 | -5,012,501 |
