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 17,961,745, 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 | 17,961,745 | |
| -1 | -17,961,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,961,745.
Example:
1 x 17,961,745 = 17,961,745
and
-1 x -17,961,745 = 17,961,745
Notice both answers equal 17,961,745
With that explanation out of the way, let's continue. Next, we take the number 17,961,745 and divide it by 2:
17,961,745 ÷ 2 = 8,980,872.5
If the quotient is a whole number, then 2 and 8,980,872.5 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 | 17,961,745 | |
| -1 | -17,961,745 |
Now, we try dividing 17,961,745 by 3:
17,961,745 ÷ 3 = 5,987,248.3333
If the quotient is a whole number, then 3 and 5,987,248.3333 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 | 17,961,745 | |
| -1 | -17,961,745 |
Let's try dividing by 4:
17,961,745 ÷ 4 = 4,490,436.25
If the quotient is a whole number, then 4 and 4,490,436.25 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 | 17,961,745 | |
| -1 | 17,961,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 817 | 4,085 | 4,397 | 21,985 | 83,543 | 189,071 | 417,715 | 945,355 | 3,592,349 | 17,961,745 |
| -1 | -5 | -19 | -43 | -95 | -215 | -817 | -4,085 | -4,397 | -21,985 | -83,543 | -189,071 | -417,715 | -945,355 | -3,592,349 | -17,961,745 |
