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 31,222,433, 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 | 31,222,433 | |
| -1 | -31,222,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,222,433.
Example:
1 x 31,222,433 = 31,222,433
and
-1 x -31,222,433 = 31,222,433
Notice both answers equal 31,222,433
With that explanation out of the way, let's continue. Next, we take the number 31,222,433 and divide it by 2:
31,222,433 ÷ 2 = 15,611,216.5
If the quotient is a whole number, then 2 and 15,611,216.5 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 | 31,222,433 | |
| -1 | -31,222,433 |
Now, we try dividing 31,222,433 by 3:
31,222,433 ÷ 3 = 10,407,477.6667
If the quotient is a whole number, then 3 and 10,407,477.6667 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 | 31,222,433 | |
| -1 | -31,222,433 |
Let's try dividing by 4:
31,222,433 ÷ 4 = 7,805,608.25
If the quotient is a whole number, then 4 and 7,805,608.25 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 | 31,222,433 | |
| -1 | 31,222,433 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 157 | 179 | 1,111 | 1,727 | 1,969 | 15,857 | 18,079 | 28,103 | 174,427 | 198,869 | 309,133 | 2,838,403 | 31,222,433 |
| -1 | -11 | -101 | -157 | -179 | -1,111 | -1,727 | -1,969 | -15,857 | -18,079 | -28,103 | -174,427 | -198,869 | -309,133 | -2,838,403 | -31,222,433 |
