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 17,558,195, 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 | 17,558,195 | |
| -1 | -17,558,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,558,195.
Example:
1 x 17,558,195 = 17,558,195
and
-1 x -17,558,195 = 17,558,195
Notice both answers equal 17,558,195
With that explanation out of the way, let's continue. Next, we take the number 17,558,195 and divide it by 2:
17,558,195 ÷ 2 = 8,779,097.5
If the quotient is a whole number, then 2 and 8,779,097.5 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 | 17,558,195 | |
| -1 | -17,558,195 |
Now, we try dividing 17,558,195 by 3:
17,558,195 ÷ 3 = 5,852,731.6667
If the quotient is a whole number, then 3 and 5,852,731.6667 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 | 17,558,195 | |
| -1 | -17,558,195 |
Let's try dividing by 4:
17,558,195 ÷ 4 = 4,389,548.75
If the quotient is a whole number, then 4 and 4,389,548.75 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 | 17,558,195 | |
| -1 | 17,558,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 29 | 85 | 145 | 289 | 419 | 493 | 1,445 | 2,095 | 2,465 | 7,123 | 8,381 | 12,151 | 35,615 | 41,905 | 60,755 | 121,091 | 206,567 | 605,455 | 1,032,835 | 3,511,639 | 17,558,195 |
| -1 | -5 | -17 | -29 | -85 | -145 | -289 | -419 | -493 | -1,445 | -2,095 | -2,465 | -7,123 | -8,381 | -12,151 | -35,615 | -41,905 | -60,755 | -121,091 | -206,567 | -605,455 | -1,032,835 | -3,511,639 | -17,558,195 |
