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 31,426,633, 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 | 31,426,633 | |
| -1 | -31,426,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,426,633.
Example:
1 x 31,426,633 = 31,426,633
and
-1 x -31,426,633 = 31,426,633
Notice both answers equal 31,426,633
With that explanation out of the way, let's continue. Next, we take the number 31,426,633 and divide it by 2:
31,426,633 ÷ 2 = 15,713,316.5
If the quotient is a whole number, then 2 and 15,713,316.5 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 | 31,426,633 | |
| -1 | -31,426,633 |
Now, we try dividing 31,426,633 by 3:
31,426,633 ÷ 3 = 10,475,544.3333
If the quotient is a whole number, then 3 and 10,475,544.3333 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 | 31,426,633 | |
| -1 | -31,426,633 |
Let's try dividing by 4:
31,426,633 ÷ 4 = 7,856,658.25
If the quotient is a whole number, then 4 and 7,856,658.25 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 | 31,426,633 | |
| -1 | 31,426,633 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 149 | 203 | 1,039 | 1,043 | 4,321 | 7,273 | 30,131 | 30,247 | 154,811 | 210,917 | 1,083,677 | 4,489,519 | 31,426,633 |
| -1 | -7 | -29 | -149 | -203 | -1,039 | -1,043 | -4,321 | -7,273 | -30,131 | -30,247 | -154,811 | -210,917 | -1,083,677 | -4,489,519 | -31,426,633 |
