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 316,000,519, 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 | 316,000,519 | |
| -1 | -316,000,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 316,000,519.
Example:
1 x 316,000,519 = 316,000,519
and
-1 x -316,000,519 = 316,000,519
Notice both answers equal 316,000,519
With that explanation out of the way, let's continue. Next, we take the number 316,000,519 and divide it by 2:
316,000,519 ÷ 2 = 158,000,259.5
If the quotient is a whole number, then 2 and 158,000,259.5 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 | 316,000,519 | |
| -1 | -316,000,519 |
Now, we try dividing 316,000,519 by 3:
316,000,519 ÷ 3 = 105,333,506.3333
If the quotient is a whole number, then 3 and 105,333,506.3333 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 | 316,000,519 | |
| -1 | -316,000,519 |
Let's try dividing by 4:
316,000,519 ÷ 4 = 79,000,129.75
If the quotient is a whole number, then 4 and 79,000,129.75 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 | 316,000,519 | |
| -1 | 316,000,519 |
If you did it right, you will end up with this table:
| 1 | 23 | 59 | 337 | 691 | 1,357 | 7,751 | 15,893 | 19,883 | 40,769 | 232,867 | 457,309 | 937,687 | 5,355,941 | 13,739,153 | 316,000,519 |
| -1 | -23 | -59 | -337 | -691 | -1,357 | -7,751 | -15,893 | -19,883 | -40,769 | -232,867 | -457,309 | -937,687 | -5,355,941 | -13,739,153 | -316,000,519 |
