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 32,013,421, 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 | 32,013,421 | |
| -1 | -32,013,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,013,421.
Example:
1 x 32,013,421 = 32,013,421
and
-1 x -32,013,421 = 32,013,421
Notice both answers equal 32,013,421
With that explanation out of the way, let's continue. Next, we take the number 32,013,421 and divide it by 2:
32,013,421 ÷ 2 = 16,006,710.5
If the quotient is a whole number, then 2 and 16,006,710.5 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 | 32,013,421 | |
| -1 | -32,013,421 |
Now, we try dividing 32,013,421 by 3:
32,013,421 ÷ 3 = 10,671,140.3333
If the quotient is a whole number, then 3 and 10,671,140.3333 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 | 32,013,421 | |
| -1 | -32,013,421 |
Let's try dividing by 4:
32,013,421 ÷ 4 = 8,003,355.25
If the quotient is a whole number, then 4 and 8,003,355.25 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 | 32,013,421 | |
| -1 | 32,013,421 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 269 | 341 | 349 | 2,959 | 3,839 | 8,339 | 10,819 | 91,729 | 93,881 | 119,009 | 1,032,691 | 2,910,311 | 32,013,421 |
| -1 | -11 | -31 | -269 | -341 | -349 | -2,959 | -3,839 | -8,339 | -10,819 | -91,729 | -93,881 | -119,009 | -1,032,691 | -2,910,311 | -32,013,421 |
