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 17,167,643, 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 | 17,167,643 | |
| -1 | -17,167,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,167,643.
Example:
1 x 17,167,643 = 17,167,643
and
-1 x -17,167,643 = 17,167,643
Notice both answers equal 17,167,643
With that explanation out of the way, let's continue. Next, we take the number 17,167,643 and divide it by 2:
17,167,643 ÷ 2 = 8,583,821.5
If the quotient is a whole number, then 2 and 8,583,821.5 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 | 17,167,643 | |
| -1 | -17,167,643 |
Now, we try dividing 17,167,643 by 3:
17,167,643 ÷ 3 = 5,722,547.6667
If the quotient is a whole number, then 3 and 5,722,547.6667 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 | 17,167,643 | |
| -1 | -17,167,643 |
Let's try dividing by 4:
17,167,643 ÷ 4 = 4,291,910.75
If the quotient is a whole number, then 4 and 4,291,910.75 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 | 17,167,643 | |
| -1 | 17,167,643 |
If you did it right, you will end up with this table:
| 1 | 41 | 47 | 59 | 151 | 1,927 | 2,419 | 2,773 | 6,191 | 7,097 | 8,909 | 113,693 | 290,977 | 365,269 | 418,723 | 17,167,643 |
| -1 | -41 | -47 | -59 | -151 | -1,927 | -2,419 | -2,773 | -6,191 | -7,097 | -8,909 | -113,693 | -290,977 | -365,269 | -418,723 | -17,167,643 |
