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 17,517,745, 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 | 17,517,745 | |
| -1 | -17,517,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,517,745.
Example:
1 x 17,517,745 = 17,517,745
and
-1 x -17,517,745 = 17,517,745
Notice both answers equal 17,517,745
With that explanation out of the way, let's continue. Next, we take the number 17,517,745 and divide it by 2:
17,517,745 ÷ 2 = 8,758,872.5
If the quotient is a whole number, then 2 and 8,758,872.5 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 | 17,517,745 | |
| -1 | -17,517,745 |
Now, we try dividing 17,517,745 by 3:
17,517,745 ÷ 3 = 5,839,248.3333
If the quotient is a whole number, then 3 and 5,839,248.3333 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 | 17,517,745 | |
| -1 | -17,517,745 |
Let's try dividing by 4:
17,517,745 ÷ 4 = 4,379,436.25
If the quotient is a whole number, then 4 and 4,379,436.25 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 | 17,517,745 | |
| -1 | 17,517,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 127 | 245 | 563 | 635 | 889 | 2,815 | 3,941 | 4,445 | 6,223 | 19,705 | 27,587 | 31,115 | 71,501 | 137,935 | 357,505 | 500,507 | 2,502,535 | 3,503,549 | 17,517,745 |
| -1 | -5 | -7 | -35 | -49 | -127 | -245 | -563 | -635 | -889 | -2,815 | -3,941 | -4,445 | -6,223 | -19,705 | -27,587 | -31,115 | -71,501 | -137,935 | -357,505 | -500,507 | -2,502,535 | -3,503,549 | -17,517,745 |
