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 1,240,031, 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 | 1,240,031 | |
| -1 | -1,240,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,240,031.
Example:
1 x 1,240,031 = 1,240,031
and
-1 x -1,240,031 = 1,240,031
Notice both answers equal 1,240,031
With that explanation out of the way, let's continue. Next, we take the number 1,240,031 and divide it by 2:
1,240,031 ÷ 2 = 620,015.5
If the quotient is a whole number, then 2 and 620,015.5 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 | 1,240,031 | |
| -1 | -1,240,031 |
Now, we try dividing 1,240,031 by 3:
1,240,031 ÷ 3 = 413,343.6667
If the quotient is a whole number, then 3 and 413,343.6667 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 | 1,240,031 | |
| -1 | -1,240,031 |
Let's try dividing by 4:
1,240,031 ÷ 4 = 310,007.75
If the quotient is a whole number, then 4 and 310,007.75 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 | 1,240,031 | |
| -1 | 1,240,031 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 31 | 181 | 221 | 403 | 527 | 2,353 | 3,077 | 5,611 | 6,851 | 40,001 | 72,943 | 95,387 | 1,240,031 |
| -1 | -13 | -17 | -31 | -181 | -221 | -403 | -527 | -2,353 | -3,077 | -5,611 | -6,851 | -40,001 | -72,943 | -95,387 | -1,240,031 |
