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 312,501,455, 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 | 312,501,455 | |
| -1 | -312,501,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 312,501,455.
Example:
1 x 312,501,455 = 312,501,455
and
-1 x -312,501,455 = 312,501,455
Notice both answers equal 312,501,455
With that explanation out of the way, let's continue. Next, we take the number 312,501,455 and divide it by 2:
312,501,455 ÷ 2 = 156,250,727.5
If the quotient is a whole number, then 2 and 156,250,727.5 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 | 312,501,455 | |
| -1 | -312,501,455 |
Now, we try dividing 312,501,455 by 3:
312,501,455 ÷ 3 = 104,167,151.6667
If the quotient is a whole number, then 3 and 104,167,151.6667 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 | 312,501,455 | |
| -1 | -312,501,455 |
Let's try dividing by 4:
312,501,455 ÷ 4 = 78,125,363.75
If the quotient is a whole number, then 4 and 78,125,363.75 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 | 312,501,455 | |
| -1 | 312,501,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 361 | 665 | 1,805 | 2,527 | 12,635 | 24,733 | 123,665 | 173,131 | 469,927 | 865,655 | 2,349,635 | 3,289,489 | 8,928,613 | 16,447,445 | 44,643,065 | 62,500,291 | 312,501,455 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -361 | -665 | -1,805 | -2,527 | -12,635 | -24,733 | -123,665 | -173,131 | -469,927 | -865,655 | -2,349,635 | -3,289,489 | -8,928,613 | -16,447,445 | -44,643,065 | -62,500,291 | -312,501,455 |
