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 32,246,155, 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 | 32,246,155 | |
| -1 | -32,246,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,246,155.
Example:
1 x 32,246,155 = 32,246,155
and
-1 x -32,246,155 = 32,246,155
Notice both answers equal 32,246,155
With that explanation out of the way, let's continue. Next, we take the number 32,246,155 and divide it by 2:
32,246,155 ÷ 2 = 16,123,077.5
If the quotient is a whole number, then 2 and 16,123,077.5 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 | 32,246,155 | |
| -1 | -32,246,155 |
Now, we try dividing 32,246,155 by 3:
32,246,155 ÷ 3 = 10,748,718.3333
If the quotient is a whole number, then 3 and 10,748,718.3333 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 | 32,246,155 | |
| -1 | -32,246,155 |
Let's try dividing by 4:
32,246,155 ÷ 4 = 8,061,538.75
If the quotient is a whole number, then 4 and 8,061,538.75 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 | 32,246,155 | |
| -1 | 32,246,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 281 | 295 | 389 | 1,405 | 1,945 | 16,579 | 22,951 | 82,895 | 109,309 | 114,755 | 546,545 | 6,449,231 | 32,246,155 |
| -1 | -5 | -59 | -281 | -295 | -389 | -1,405 | -1,945 | -16,579 | -22,951 | -82,895 | -109,309 | -114,755 | -546,545 | -6,449,231 | -32,246,155 |
