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 32,149,843, 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 | 32,149,843 | |
| -1 | -32,149,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,149,843.
Example:
1 x 32,149,843 = 32,149,843
and
-1 x -32,149,843 = 32,149,843
Notice both answers equal 32,149,843
With that explanation out of the way, let's continue. Next, we take the number 32,149,843 and divide it by 2:
32,149,843 ÷ 2 = 16,074,921.5
If the quotient is a whole number, then 2 and 16,074,921.5 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 | 32,149,843 | |
| -1 | -32,149,843 |
Now, we try dividing 32,149,843 by 3:
32,149,843 ÷ 3 = 10,716,614.3333
If the quotient is a whole number, then 3 and 10,716,614.3333 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 | 32,149,843 | |
| -1 | -32,149,843 |
Let's try dividing by 4:
32,149,843 ÷ 4 = 8,037,460.75
If the quotient is a whole number, then 4 and 8,037,460.75 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 | 32,149,843 | |
| -1 | 32,149,843 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 199 | 209 | 773 | 2,189 | 3,781 | 8,503 | 14,687 | 41,591 | 153,827 | 161,557 | 1,692,097 | 2,922,713 | 32,149,843 |
| -1 | -11 | -19 | -199 | -209 | -773 | -2,189 | -3,781 | -8,503 | -14,687 | -41,591 | -153,827 | -161,557 | -1,692,097 | -2,922,713 | -32,149,843 |
