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 520,162,447, 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 | 520,162,447 | |
| -1 | -520,162,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,162,447.
Example:
1 x 520,162,447 = 520,162,447
and
-1 x -520,162,447 = 520,162,447
Notice both answers equal 520,162,447
With that explanation out of the way, let's continue. Next, we take the number 520,162,447 and divide it by 2:
520,162,447 ÷ 2 = 260,081,223.5
If the quotient is a whole number, then 2 and 260,081,223.5 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 | 520,162,447 | |
| -1 | -520,162,447 |
Now, we try dividing 520,162,447 by 3:
520,162,447 ÷ 3 = 173,387,482.3333
If the quotient is a whole number, then 3 and 173,387,482.3333 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 | 520,162,447 | |
| -1 | -520,162,447 |
Let's try dividing by 4:
520,162,447 ÷ 4 = 130,040,611.75
If the quotient is a whole number, then 4 and 130,040,611.75 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 | 520,162,447 | |
| -1 | 520,162,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 317 | 2,219 | 5,389 | 13,789 | 37,723 | 96,523 | 234,413 | 1,640,891 | 4,371,113 | 30,597,791 | 74,308,921 | 520,162,447 |
| -1 | -7 | -17 | -119 | -317 | -2,219 | -5,389 | -13,789 | -37,723 | -96,523 | -234,413 | -1,640,891 | -4,371,113 | -30,597,791 | -74,308,921 | -520,162,447 |
