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 7,090,499, 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 | 7,090,499 | |
| -1 | -7,090,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,090,499.
Example:
1 x 7,090,499 = 7,090,499
and
-1 x -7,090,499 = 7,090,499
Notice both answers equal 7,090,499
With that explanation out of the way, let's continue. Next, we take the number 7,090,499 and divide it by 2:
7,090,499 ÷ 2 = 3,545,249.5
If the quotient is a whole number, then 2 and 3,545,249.5 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 | 7,090,499 | |
| -1 | -7,090,499 |
Now, we try dividing 7,090,499 by 3:
7,090,499 ÷ 3 = 2,363,499.6667
If the quotient is a whole number, then 3 and 2,363,499.6667 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 | 7,090,499 | |
| -1 | -7,090,499 |
Let's try dividing by 4:
7,090,499 ÷ 4 = 1,772,624.75
If the quotient is a whole number, then 4 and 1,772,624.75 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 | 7,090,499 | |
| -1 | 7,090,499 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 53 | 251 | 533 | 689 | 2,173 | 3,263 | 10,291 | 13,303 | 28,249 | 133,783 | 172,939 | 545,423 | 7,090,499 |
| -1 | -13 | -41 | -53 | -251 | -533 | -689 | -2,173 | -3,263 | -10,291 | -13,303 | -28,249 | -133,783 | -172,939 | -545,423 | -7,090,499 |
