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 31,226,083, 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 | 31,226,083 | |
| -1 | -31,226,083 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,226,083.
Example:
1 x 31,226,083 = 31,226,083
and
-1 x -31,226,083 = 31,226,083
Notice both answers equal 31,226,083
With that explanation out of the way, let's continue. Next, we take the number 31,226,083 and divide it by 2:
31,226,083 ÷ 2 = 15,613,041.5
If the quotient is a whole number, then 2 and 15,613,041.5 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 | 31,226,083 | |
| -1 | -31,226,083 |
Now, we try dividing 31,226,083 by 3:
31,226,083 ÷ 3 = 10,408,694.3333
If the quotient is a whole number, then 3 and 10,408,694.3333 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 | 31,226,083 | |
| -1 | -31,226,083 |
Let's try dividing by 4:
31,226,083 ÷ 4 = 7,806,520.75
If the quotient is a whole number, then 4 and 7,806,520.75 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 | 31,226,083 | |
| -1 | 31,226,083 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 61 | 217 | 337 | 427 | 1,519 | 1,891 | 2,359 | 2,989 | 10,447 | 13,237 | 16,513 | 20,557 | 73,129 | 92,659 | 143,899 | 511,903 | 637,267 | 1,007,293 | 4,460,869 | 31,226,083 |
| -1 | -7 | -31 | -49 | -61 | -217 | -337 | -427 | -1,519 | -1,891 | -2,359 | -2,989 | -10,447 | -13,237 | -16,513 | -20,557 | -73,129 | -92,659 | -143,899 | -511,903 | -637,267 | -1,007,293 | -4,460,869 | -31,226,083 |
