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 34,404,515, 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 | 34,404,515 | |
| -1 | -34,404,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,404,515.
Example:
1 x 34,404,515 = 34,404,515
and
-1 x -34,404,515 = 34,404,515
Notice both answers equal 34,404,515
With that explanation out of the way, let's continue. Next, we take the number 34,404,515 and divide it by 2:
34,404,515 ÷ 2 = 17,202,257.5
If the quotient is a whole number, then 2 and 17,202,257.5 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 | 34,404,515 | |
| -1 | -34,404,515 |
Now, we try dividing 34,404,515 by 3:
34,404,515 ÷ 3 = 11,468,171.6667
If the quotient is a whole number, then 3 and 11,468,171.6667 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 | 34,404,515 | |
| -1 | -34,404,515 |
Let's try dividing by 4:
34,404,515 ÷ 4 = 8,601,128.75
If the quotient is a whole number, then 4 and 8,601,128.75 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 | 34,404,515 | |
| -1 | 34,404,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 3,655 | 9,413 | 47,065 | 160,021 | 404,759 | 800,105 | 2,023,795 | 6,880,903 | 34,404,515 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -3,655 | -9,413 | -47,065 | -160,021 | -404,759 | -800,105 | -2,023,795 | -6,880,903 | -34,404,515 |
