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 31,432,135, 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 | 31,432,135 | |
| -1 | -31,432,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,432,135.
Example:
1 x 31,432,135 = 31,432,135
and
-1 x -31,432,135 = 31,432,135
Notice both answers equal 31,432,135
With that explanation out of the way, let's continue. Next, we take the number 31,432,135 and divide it by 2:
31,432,135 ÷ 2 = 15,716,067.5
If the quotient is a whole number, then 2 and 15,716,067.5 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 | 31,432,135 | |
| -1 | -31,432,135 |
Now, we try dividing 31,432,135 by 3:
31,432,135 ÷ 3 = 10,477,378.3333
If the quotient is a whole number, then 3 and 10,477,378.3333 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 | 31,432,135 | |
| -1 | -31,432,135 |
Let's try dividing by 4:
31,432,135 ÷ 4 = 7,858,033.75
If the quotient is a whole number, then 4 and 7,858,033.75 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 | 31,432,135 | |
| -1 | 31,432,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 317 | 1,585 | 2,219 | 2,833 | 11,095 | 14,165 | 19,831 | 99,155 | 898,061 | 4,490,305 | 6,286,427 | 31,432,135 |
| -1 | -5 | -7 | -35 | -317 | -1,585 | -2,219 | -2,833 | -11,095 | -14,165 | -19,831 | -99,155 | -898,061 | -4,490,305 | -6,286,427 | -31,432,135 |
