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 3,231,943, 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 | 3,231,943 | |
| -1 | -3,231,943 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,231,943.
Example:
1 x 3,231,943 = 3,231,943
and
-1 x -3,231,943 = 3,231,943
Notice both answers equal 3,231,943
With that explanation out of the way, let's continue. Next, we take the number 3,231,943 and divide it by 2:
3,231,943 ÷ 2 = 1,615,971.5
If the quotient is a whole number, then 2 and 1,615,971.5 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 | 3,231,943 | |
| -1 | -3,231,943 |
Now, we try dividing 3,231,943 by 3:
3,231,943 ÷ 3 = 1,077,314.3333
If the quotient is a whole number, then 3 and 1,077,314.3333 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 | 3,231,943 | |
| -1 | -3,231,943 |
Let's try dividing by 4:
3,231,943 ÷ 4 = 807,985.75
If the quotient is a whole number, then 4 and 807,985.75 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 | 3,231,943 | |
| -1 | 3,231,943 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 97 | 143 | 233 | 1,067 | 1,261 | 2,563 | 3,029 | 13,871 | 22,601 | 33,319 | 248,611 | 293,813 | 3,231,943 |
| -1 | -11 | -13 | -97 | -143 | -233 | -1,067 | -1,261 | -2,563 | -3,029 | -13,871 | -22,601 | -33,319 | -248,611 | -293,813 | -3,231,943 |
