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 457,808,515, 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 | 457,808,515 | |
| -1 | -457,808,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 457,808,515.
Example:
1 x 457,808,515 = 457,808,515
and
-1 x -457,808,515 = 457,808,515
Notice both answers equal 457,808,515
With that explanation out of the way, let's continue. Next, we take the number 457,808,515 and divide it by 2:
457,808,515 ÷ 2 = 228,904,257.5
If the quotient is a whole number, then 2 and 228,904,257.5 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 | 457,808,515 | |
| -1 | -457,808,515 |
Now, we try dividing 457,808,515 by 3:
457,808,515 ÷ 3 = 152,602,838.3333
If the quotient is a whole number, then 3 and 152,602,838.3333 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 | 457,808,515 | |
| -1 | -457,808,515 |
Let's try dividing by 4:
457,808,515 ÷ 4 = 114,452,128.75
If the quotient is a whole number, then 4 and 114,452,128.75 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 | 457,808,515 | |
| -1 | 457,808,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,093 | 4,409 | 5,465 | 20,767 | 22,045 | 83,771 | 103,835 | 418,855 | 4,819,037 | 24,095,185 | 91,561,703 | 457,808,515 |
| -1 | -5 | -19 | -95 | -1,093 | -4,409 | -5,465 | -20,767 | -22,045 | -83,771 | -103,835 | -418,855 | -4,819,037 | -24,095,185 | -91,561,703 | -457,808,515 |
