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 17,756,545, 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 | 17,756,545 | |
| -1 | -17,756,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,756,545.
Example:
1 x 17,756,545 = 17,756,545
and
-1 x -17,756,545 = 17,756,545
Notice both answers equal 17,756,545
With that explanation out of the way, let's continue. Next, we take the number 17,756,545 and divide it by 2:
17,756,545 ÷ 2 = 8,878,272.5
If the quotient is a whole number, then 2 and 8,878,272.5 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 | 17,756,545 | |
| -1 | -17,756,545 |
Now, we try dividing 17,756,545 by 3:
17,756,545 ÷ 3 = 5,918,848.3333
If the quotient is a whole number, then 3 and 5,918,848.3333 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 | 17,756,545 | |
| -1 | -17,756,545 |
Let's try dividing by 4:
17,756,545 ÷ 4 = 4,439,136.25
If the quotient is a whole number, then 4 and 4,439,136.25 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 | 17,756,545 | |
| -1 | 17,756,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 311 | 601 | 1,555 | 3,005 | 5,909 | 11,419 | 29,545 | 57,095 | 186,911 | 934,555 | 3,551,309 | 17,756,545 |
| -1 | -5 | -19 | -95 | -311 | -601 | -1,555 | -3,005 | -5,909 | -11,419 | -29,545 | -57,095 | -186,911 | -934,555 | -3,551,309 | -17,756,545 |
