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 312,470,249, 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 | 312,470,249 | |
| -1 | -312,470,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 312,470,249.
Example:
1 x 312,470,249 = 312,470,249
and
-1 x -312,470,249 = 312,470,249
Notice both answers equal 312,470,249
With that explanation out of the way, let's continue. Next, we take the number 312,470,249 and divide it by 2:
312,470,249 ÷ 2 = 156,235,124.5
If the quotient is a whole number, then 2 and 156,235,124.5 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 | 312,470,249 | |
| -1 | -312,470,249 |
Now, we try dividing 312,470,249 by 3:
312,470,249 ÷ 3 = 104,156,749.6667
If the quotient is a whole number, then 3 and 104,156,749.6667 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 | 312,470,249 | |
| -1 | -312,470,249 |
Let's try dividing by 4:
312,470,249 ÷ 4 = 78,117,562.25
If the quotient is a whole number, then 4 and 78,117,562.25 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 | 312,470,249 | |
| -1 | 312,470,249 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 529 | 2,093 | 3,703 | 6,491 | 6,877 | 45,437 | 48,139 | 84,383 | 149,293 | 590,681 | 1,045,051 | 1,940,809 | 3,433,739 | 13,585,663 | 24,036,173 | 44,638,607 | 312,470,249 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -529 | -2,093 | -3,703 | -6,491 | -6,877 | -45,437 | -48,139 | -84,383 | -149,293 | -590,681 | -1,045,051 | -1,940,809 | -3,433,739 | -13,585,663 | -24,036,173 | -44,638,607 | -312,470,249 |
