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 47,031,305, 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 | 47,031,305 | |
| -1 | -47,031,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,031,305.
Example:
1 x 47,031,305 = 47,031,305
and
-1 x -47,031,305 = 47,031,305
Notice both answers equal 47,031,305
With that explanation out of the way, let's continue. Next, we take the number 47,031,305 and divide it by 2:
47,031,305 ÷ 2 = 23,515,652.5
If the quotient is a whole number, then 2 and 23,515,652.5 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 | 47,031,305 | |
| -1 | -47,031,305 |
Now, we try dividing 47,031,305 by 3:
47,031,305 ÷ 3 = 15,677,101.6667
If the quotient is a whole number, then 3 and 15,677,101.6667 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 | 47,031,305 | |
| -1 | -47,031,305 |
Let's try dividing by 4:
47,031,305 ÷ 4 = 11,757,826.25
If the quotient is a whole number, then 4 and 11,757,826.25 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 | 47,031,305 | |
| -1 | 47,031,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 61 | 205 | 305 | 2,501 | 3,761 | 12,505 | 18,805 | 154,201 | 229,421 | 771,005 | 1,147,105 | 9,406,261 | 47,031,305 |
| -1 | -5 | -41 | -61 | -205 | -305 | -2,501 | -3,761 | -12,505 | -18,805 | -154,201 | -229,421 | -771,005 | -1,147,105 | -9,406,261 | -47,031,305 |
