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 31,347,043, 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 | 31,347,043 | |
| -1 | -31,347,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,347,043.
Example:
1 x 31,347,043 = 31,347,043
and
-1 x -31,347,043 = 31,347,043
Notice both answers equal 31,347,043
With that explanation out of the way, let's continue. Next, we take the number 31,347,043 and divide it by 2:
31,347,043 ÷ 2 = 15,673,521.5
If the quotient is a whole number, then 2 and 15,673,521.5 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 | 31,347,043 | |
| -1 | -31,347,043 |
Now, we try dividing 31,347,043 by 3:
31,347,043 ÷ 3 = 10,449,014.3333
If the quotient is a whole number, then 3 and 10,449,014.3333 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 | 31,347,043 | |
| -1 | -31,347,043 |
Let's try dividing by 4:
31,347,043 ÷ 4 = 7,836,760.75
If the quotient is a whole number, then 4 and 7,836,760.75 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 | 31,347,043 | |
| -1 | 31,347,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 91 | 301 | 559 | 3,913 | 8,011 | 56,077 | 104,143 | 344,473 | 729,001 | 2,411,311 | 4,478,149 | 31,347,043 |
| -1 | -7 | -13 | -43 | -91 | -301 | -559 | -3,913 | -8,011 | -56,077 | -104,143 | -344,473 | -729,001 | -2,411,311 | -4,478,149 | -31,347,043 |
