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 7,192,087, 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 | 7,192,087 | |
| -1 | -7,192,087 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,192,087.
Example:
1 x 7,192,087 = 7,192,087
and
-1 x -7,192,087 = 7,192,087
Notice both answers equal 7,192,087
With that explanation out of the way, let's continue. Next, we take the number 7,192,087 and divide it by 2:
7,192,087 ÷ 2 = 3,596,043.5
If the quotient is a whole number, then 2 and 3,596,043.5 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 | 7,192,087 | |
| -1 | -7,192,087 |
Now, we try dividing 7,192,087 by 3:
7,192,087 ÷ 3 = 2,397,362.3333
If the quotient is a whole number, then 3 and 2,397,362.3333 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 | 7,192,087 | |
| -1 | -7,192,087 |
Let's try dividing by 4:
7,192,087 ÷ 4 = 1,798,021.75
If the quotient is a whole number, then 4 and 1,798,021.75 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 | 7,192,087 | |
| -1 | 7,192,087 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 71 | 203 | 497 | 499 | 2,059 | 3,493 | 14,413 | 14,471 | 35,429 | 101,297 | 248,003 | 1,027,441 | 7,192,087 |
| -1 | -7 | -29 | -71 | -203 | -497 | -499 | -2,059 | -3,493 | -14,413 | -14,471 | -35,429 | -101,297 | -248,003 | -1,027,441 | -7,192,087 |
