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 8,418,499, 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 | 8,418,499 | |
| -1 | -8,418,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,418,499.
Example:
1 x 8,418,499 = 8,418,499
and
-1 x -8,418,499 = 8,418,499
Notice both answers equal 8,418,499
With that explanation out of the way, let's continue. Next, we take the number 8,418,499 and divide it by 2:
8,418,499 ÷ 2 = 4,209,249.5
If the quotient is a whole number, then 2 and 4,209,249.5 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 | 8,418,499 | |
| -1 | -8,418,499 |
Now, we try dividing 8,418,499 by 3:
8,418,499 ÷ 3 = 2,806,166.3333
If the quotient is a whole number, then 3 and 2,806,166.3333 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 | 8,418,499 | |
| -1 | -8,418,499 |
Let's try dividing by 4:
8,418,499 ÷ 4 = 2,104,624.75
If the quotient is a whole number, then 4 and 2,104,624.75 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 | 8,418,499 | |
| -1 | 8,418,499 |
If you did it right, you will end up with this table:
| 1 | 37 | 47 | 103 | 1,739 | 2,209 | 3,811 | 4,841 | 81,733 | 179,117 | 227,527 | 8,418,499 |
| -1 | -37 | -47 | -103 | -1,739 | -2,209 | -3,811 | -4,841 | -81,733 | -179,117 | -227,527 | -8,418,499 |
