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 17,229,505, 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 | 17,229,505 | |
| -1 | -17,229,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,229,505.
Example:
1 x 17,229,505 = 17,229,505
and
-1 x -17,229,505 = 17,229,505
Notice both answers equal 17,229,505
With that explanation out of the way, let's continue. Next, we take the number 17,229,505 and divide it by 2:
17,229,505 ÷ 2 = 8,614,752.5
If the quotient is a whole number, then 2 and 8,614,752.5 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 | 17,229,505 | |
| -1 | -17,229,505 |
Now, we try dividing 17,229,505 by 3:
17,229,505 ÷ 3 = 5,743,168.3333
If the quotient is a whole number, then 3 and 5,743,168.3333 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 | 17,229,505 | |
| -1 | -17,229,505 |
Let's try dividing by 4:
17,229,505 ÷ 4 = 4,307,376.25
If the quotient is a whole number, then 4 and 4,307,376.25 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 | 17,229,505 | |
| -1 | 17,229,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 79 | 265 | 395 | 823 | 4,115 | 4,187 | 20,935 | 43,619 | 65,017 | 218,095 | 325,085 | 3,445,901 | 17,229,505 |
| -1 | -5 | -53 | -79 | -265 | -395 | -823 | -4,115 | -4,187 | -20,935 | -43,619 | -65,017 | -218,095 | -325,085 | -3,445,901 | -17,229,505 |
