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 312,788,063, 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 | 312,788,063 | |
| -1 | -312,788,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 312,788,063.
Example:
1 x 312,788,063 = 312,788,063
and
-1 x -312,788,063 = 312,788,063
Notice both answers equal 312,788,063
With that explanation out of the way, let's continue. Next, we take the number 312,788,063 and divide it by 2:
312,788,063 ÷ 2 = 156,394,031.5
If the quotient is a whole number, then 2 and 156,394,031.5 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 | 312,788,063 | |
| -1 | -312,788,063 |
Now, we try dividing 312,788,063 by 3:
312,788,063 ÷ 3 = 104,262,687.6667
If the quotient is a whole number, then 3 and 104,262,687.6667 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 | 312,788,063 | |
| -1 | -312,788,063 |
Let's try dividing by 4:
312,788,063 ÷ 4 = 78,197,015.75
If the quotient is a whole number, then 4 and 78,197,015.75 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 | 312,788,063 | |
| -1 | 312,788,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 43 | 161 | 301 | 989 | 6,923 | 45,181 | 316,267 | 1,039,163 | 1,942,783 | 7,274,141 | 13,599,481 | 44,684,009 | 312,788,063 |
| -1 | -7 | -23 | -43 | -161 | -301 | -989 | -6,923 | -45,181 | -316,267 | -1,039,163 | -1,942,783 | -7,274,141 | -13,599,481 | -44,684,009 | -312,788,063 |
