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 17,817,095, 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 | 17,817,095 | |
| -1 | -17,817,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,817,095.
Example:
1 x 17,817,095 = 17,817,095
and
-1 x -17,817,095 = 17,817,095
Notice both answers equal 17,817,095
With that explanation out of the way, let's continue. Next, we take the number 17,817,095 and divide it by 2:
17,817,095 ÷ 2 = 8,908,547.5
If the quotient is a whole number, then 2 and 8,908,547.5 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 | 17,817,095 | |
| -1 | -17,817,095 |
Now, we try dividing 17,817,095 by 3:
17,817,095 ÷ 3 = 5,939,031.6667
If the quotient is a whole number, then 3 and 5,939,031.6667 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 | 17,817,095 | |
| -1 | -17,817,095 |
Let's try dividing by 4:
17,817,095 ÷ 4 = 4,454,273.75
If the quotient is a whole number, then 4 and 4,454,273.75 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 | 17,817,095 | |
| -1 | 17,817,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 71 | 155 | 355 | 1,619 | 2,201 | 8,095 | 11,005 | 50,189 | 114,949 | 250,945 | 574,745 | 3,563,419 | 17,817,095 |
| -1 | -5 | -31 | -71 | -155 | -355 | -1,619 | -2,201 | -8,095 | -11,005 | -50,189 | -114,949 | -250,945 | -574,745 | -3,563,419 | -17,817,095 |
