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 524,406,509, 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 | 524,406,509 | |
| -1 | -524,406,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 524,406,509.
Example:
1 x 524,406,509 = 524,406,509
and
-1 x -524,406,509 = 524,406,509
Notice both answers equal 524,406,509
With that explanation out of the way, let's continue. Next, we take the number 524,406,509 and divide it by 2:
524,406,509 ÷ 2 = 262,203,254.5
If the quotient is a whole number, then 2 and 262,203,254.5 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 | 524,406,509 | |
| -1 | -524,406,509 |
Now, we try dividing 524,406,509 by 3:
524,406,509 ÷ 3 = 174,802,169.6667
If the quotient is a whole number, then 3 and 174,802,169.6667 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 | 524,406,509 | |
| -1 | -524,406,509 |
Let's try dividing by 4:
524,406,509 ÷ 4 = 131,101,627.25
If the quotient is a whole number, then 4 and 131,101,627.25 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 | 524,406,509 | |
| -1 | 524,406,509 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 31 | 253 | 341 | 713 | 7,843 | 66,863 | 735,493 | 1,537,849 | 2,072,753 | 16,916,339 | 22,800,283 | 47,673,319 | 524,406,509 |
| -1 | -11 | -23 | -31 | -253 | -341 | -713 | -7,843 | -66,863 | -735,493 | -1,537,849 | -2,072,753 | -16,916,339 | -22,800,283 | -47,673,319 | -524,406,509 |
