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 32,487,293, 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 | 32,487,293 | |
| -1 | -32,487,293 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,487,293.
Example:
1 x 32,487,293 = 32,487,293
and
-1 x -32,487,293 = 32,487,293
Notice both answers equal 32,487,293
With that explanation out of the way, let's continue. Next, we take the number 32,487,293 and divide it by 2:
32,487,293 ÷ 2 = 16,243,646.5
If the quotient is a whole number, then 2 and 16,243,646.5 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 | 32,487,293 | |
| -1 | -32,487,293 |
Now, we try dividing 32,487,293 by 3:
32,487,293 ÷ 3 = 10,829,097.6667
If the quotient is a whole number, then 3 and 10,829,097.6667 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 | 32,487,293 | |
| -1 | -32,487,293 |
Let's try dividing by 4:
32,487,293 ÷ 4 = 8,121,823.25
If the quotient is a whole number, then 4 and 8,121,823.25 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 | 32,487,293 | |
| -1 | 32,487,293 |
If you did it right, you will end up with this table:
| 1 | 23 | 41 | 47 | 733 | 943 | 1,081 | 1,927 | 16,859 | 30,053 | 34,451 | 44,321 | 691,219 | 792,373 | 1,412,491 | 32,487,293 |
| -1 | -23 | -41 | -47 | -733 | -943 | -1,081 | -1,927 | -16,859 | -30,053 | -34,451 | -44,321 | -691,219 | -792,373 | -1,412,491 | -32,487,293 |
