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 520,565,201, 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 | 520,565,201 | |
| -1 | -520,565,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,565,201.
Example:
1 x 520,565,201 = 520,565,201
and
-1 x -520,565,201 = 520,565,201
Notice both answers equal 520,565,201
With that explanation out of the way, let's continue. Next, we take the number 520,565,201 and divide it by 2:
520,565,201 ÷ 2 = 260,282,600.5
If the quotient is a whole number, then 2 and 260,282,600.5 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 | 520,565,201 | |
| -1 | -520,565,201 |
Now, we try dividing 520,565,201 by 3:
520,565,201 ÷ 3 = 173,521,733.6667
If the quotient is a whole number, then 3 and 173,521,733.6667 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 | 520,565,201 | |
| -1 | -520,565,201 |
Let's try dividing by 4:
520,565,201 ÷ 4 = 130,141,300.25
If the quotient is a whole number, then 4 and 130,141,300.25 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 | 520,565,201 | |
| -1 | 520,565,201 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 647 | 767 | 1,049 | 8,411 | 13,637 | 38,173 | 61,891 | 496,249 | 678,703 | 804,583 | 8,823,139 | 40,043,477 | 520,565,201 |
| -1 | -13 | -59 | -647 | -767 | -1,049 | -8,411 | -13,637 | -38,173 | -61,891 | -496,249 | -678,703 | -804,583 | -8,823,139 | -40,043,477 | -520,565,201 |
