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 316,750,775, 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 | 316,750,775 | |
| -1 | -316,750,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 316,750,775.
Example:
1 x 316,750,775 = 316,750,775
and
-1 x -316,750,775 = 316,750,775
Notice both answers equal 316,750,775
With that explanation out of the way, let's continue. Next, we take the number 316,750,775 and divide it by 2:
316,750,775 ÷ 2 = 158,375,387.5
If the quotient is a whole number, then 2 and 158,375,387.5 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 | 316,750,775 | |
| -1 | -316,750,775 |
Now, we try dividing 316,750,775 by 3:
316,750,775 ÷ 3 = 105,583,591.6667
If the quotient is a whole number, then 3 and 105,583,591.6667 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 | 316,750,775 | |
| -1 | -316,750,775 |
Let's try dividing by 4:
316,750,775 ÷ 4 = 79,187,693.75
If the quotient is a whole number, then 4 and 79,187,693.75 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 | 316,750,775 | |
| -1 | 316,750,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 104,711 | 523,555 | 1,151,821 | 2,617,775 | 5,759,105 | 12,670,031 | 28,795,525 | 63,350,155 | 316,750,775 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -104,711 | -523,555 | -1,151,821 | -2,617,775 | -5,759,105 | -12,670,031 | -28,795,525 | -63,350,155 | -316,750,775 |
