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 5,241,509, 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 | 5,241,509 | |
| -1 | -5,241,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,241,509.
Example:
1 x 5,241,509 = 5,241,509
and
-1 x -5,241,509 = 5,241,509
Notice both answers equal 5,241,509
With that explanation out of the way, let's continue. Next, we take the number 5,241,509 and divide it by 2:
5,241,509 ÷ 2 = 2,620,754.5
If the quotient is a whole number, then 2 and 2,620,754.5 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 | 5,241,509 | |
| -1 | -5,241,509 |
Now, we try dividing 5,241,509 by 3:
5,241,509 ÷ 3 = 1,747,169.6667
If the quotient is a whole number, then 3 and 1,747,169.6667 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 | 5,241,509 | |
| -1 | -5,241,509 |
Let's try dividing by 4:
5,241,509 ÷ 4 = 1,310,377.25
If the quotient is a whole number, then 4 and 1,310,377.25 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 | 5,241,509 | |
| -1 | 5,241,509 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 239 | 241 | 1,673 | 1,687 | 3,107 | 3,133 | 21,749 | 21,931 | 57,599 | 403,193 | 748,787 | 5,241,509 |
| -1 | -7 | -13 | -91 | -239 | -241 | -1,673 | -1,687 | -3,107 | -3,133 | -21,749 | -21,931 | -57,599 | -403,193 | -748,787 | -5,241,509 |
