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 7,098,095, 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 | 7,098,095 | |
| -1 | -7,098,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,098,095.
Example:
1 x 7,098,095 = 7,098,095
and
-1 x -7,098,095 = 7,098,095
Notice both answers equal 7,098,095
With that explanation out of the way, let's continue. Next, we take the number 7,098,095 and divide it by 2:
7,098,095 ÷ 2 = 3,549,047.5
If the quotient is a whole number, then 2 and 3,549,047.5 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 | 7,098,095 | |
| -1 | -7,098,095 |
Now, we try dividing 7,098,095 by 3:
7,098,095 ÷ 3 = 2,366,031.6667
If the quotient is a whole number, then 3 and 2,366,031.6667 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 | 7,098,095 | |
| -1 | -7,098,095 |
Let's try dividing by 4:
7,098,095 ÷ 4 = 1,774,523.75
If the quotient is a whole number, then 4 and 1,774,523.75 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 | 7,098,095 | |
| -1 | 7,098,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 113 | 565 | 739 | 1,921 | 3,695 | 9,605 | 12,563 | 62,815 | 83,507 | 417,535 | 1,419,619 | 7,098,095 |
| -1 | -5 | -17 | -85 | -113 | -565 | -739 | -1,921 | -3,695 | -9,605 | -12,563 | -62,815 | -83,507 | -417,535 | -1,419,619 | -7,098,095 |
