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 457,352,285, 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 | 457,352,285 | |
| -1 | -457,352,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 457,352,285.
Example:
1 x 457,352,285 = 457,352,285
and
-1 x -457,352,285 = 457,352,285
Notice both answers equal 457,352,285
With that explanation out of the way, let's continue. Next, we take the number 457,352,285 and divide it by 2:
457,352,285 ÷ 2 = 228,676,142.5
If the quotient is a whole number, then 2 and 228,676,142.5 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 | 457,352,285 | |
| -1 | -457,352,285 |
Now, we try dividing 457,352,285 by 3:
457,352,285 ÷ 3 = 152,450,761.6667
If the quotient is a whole number, then 3 and 152,450,761.6667 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 | 457,352,285 | |
| -1 | -457,352,285 |
Let's try dividing by 4:
457,352,285 ÷ 4 = 114,338,071.25
If the quotient is a whole number, then 4 and 114,338,071.25 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 | 457,352,285 | |
| -1 | 457,352,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 349 | 1,745 | 4,537 | 20,161 | 22,685 | 100,805 | 262,093 | 1,310,465 | 7,036,189 | 35,180,945 | 91,470,457 | 457,352,285 |
| -1 | -5 | -13 | -65 | -349 | -1,745 | -4,537 | -20,161 | -22,685 | -100,805 | -262,093 | -1,310,465 | -7,036,189 | -35,180,945 | -91,470,457 | -457,352,285 |
