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 34,280,081, 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 | 34,280,081 | |
| -1 | -34,280,081 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,280,081.
Example:
1 x 34,280,081 = 34,280,081
and
-1 x -34,280,081 = 34,280,081
Notice both answers equal 34,280,081
With that explanation out of the way, let's continue. Next, we take the number 34,280,081 and divide it by 2:
34,280,081 ÷ 2 = 17,140,040.5
If the quotient is a whole number, then 2 and 17,140,040.5 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 | 34,280,081 | |
| -1 | -34,280,081 |
Now, we try dividing 34,280,081 by 3:
34,280,081 ÷ 3 = 11,426,693.6667
If the quotient is a whole number, then 3 and 11,426,693.6667 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 | 34,280,081 | |
| -1 | -34,280,081 |
Let's try dividing by 4:
34,280,081 ÷ 4 = 8,570,020.25
If the quotient is a whole number, then 4 and 8,570,020.25 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 | 34,280,081 | |
| -1 | 34,280,081 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 193 | 241 | 737 | 2,123 | 2,651 | 12,931 | 16,147 | 46,513 | 142,241 | 177,617 | 511,643 | 3,116,371 | 34,280,081 |
| -1 | -11 | -67 | -193 | -241 | -737 | -2,123 | -2,651 | -12,931 | -16,147 | -46,513 | -142,241 | -177,617 | -511,643 | -3,116,371 | -34,280,081 |
