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 31,504,445, 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 | 31,504,445 | |
| -1 | -31,504,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,504,445.
Example:
1 x 31,504,445 = 31,504,445
and
-1 x -31,504,445 = 31,504,445
Notice both answers equal 31,504,445
With that explanation out of the way, let's continue. Next, we take the number 31,504,445 and divide it by 2:
31,504,445 ÷ 2 = 15,752,222.5
If the quotient is a whole number, then 2 and 15,752,222.5 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 | 31,504,445 | |
| -1 | -31,504,445 |
Now, we try dividing 31,504,445 by 3:
31,504,445 ÷ 3 = 10,501,481.6667
If the quotient is a whole number, then 3 and 10,501,481.6667 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 | 31,504,445 | |
| -1 | -31,504,445 |
Let's try dividing by 4:
31,504,445 ÷ 4 = 7,876,111.25
If the quotient is a whole number, then 4 and 7,876,111.25 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 | 31,504,445 | |
| -1 | 31,504,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 337 | 1,685 | 2,359 | 2,671 | 11,795 | 13,355 | 18,697 | 93,485 | 900,127 | 4,500,635 | 6,300,889 | 31,504,445 |
| -1 | -5 | -7 | -35 | -337 | -1,685 | -2,359 | -2,671 | -11,795 | -13,355 | -18,697 | -93,485 | -900,127 | -4,500,635 | -6,300,889 | -31,504,445 |
