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 17,457,505, 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 | 17,457,505 | |
| -1 | -17,457,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,457,505.
Example:
1 x 17,457,505 = 17,457,505
and
-1 x -17,457,505 = 17,457,505
Notice both answers equal 17,457,505
With that explanation out of the way, let's continue. Next, we take the number 17,457,505 and divide it by 2:
17,457,505 ÷ 2 = 8,728,752.5
If the quotient is a whole number, then 2 and 8,728,752.5 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 | 17,457,505 | |
| -1 | -17,457,505 |
Now, we try dividing 17,457,505 by 3:
17,457,505 ÷ 3 = 5,819,168.3333
If the quotient is a whole number, then 3 and 5,819,168.3333 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 | 17,457,505 | |
| -1 | -17,457,505 |
Let's try dividing by 4:
17,457,505 ÷ 4 = 4,364,376.25
If the quotient is a whole number, then 4 and 4,364,376.25 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 | 17,457,505 | |
| -1 | 17,457,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 491 | 547 | 2,455 | 2,735 | 6,383 | 7,111 | 31,915 | 35,555 | 268,577 | 1,342,885 | 3,491,501 | 17,457,505 |
| -1 | -5 | -13 | -65 | -491 | -547 | -2,455 | -2,735 | -6,383 | -7,111 | -31,915 | -35,555 | -268,577 | -1,342,885 | -3,491,501 | -17,457,505 |
