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 8,118,451, 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 | 8,118,451 | |
| -1 | -8,118,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,118,451.
Example:
1 x 8,118,451 = 8,118,451
and
-1 x -8,118,451 = 8,118,451
Notice both answers equal 8,118,451
With that explanation out of the way, let's continue. Next, we take the number 8,118,451 and divide it by 2:
8,118,451 ÷ 2 = 4,059,225.5
If the quotient is a whole number, then 2 and 4,059,225.5 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 | 8,118,451 | |
| -1 | -8,118,451 |
Now, we try dividing 8,118,451 by 3:
8,118,451 ÷ 3 = 2,706,150.3333
If the quotient is a whole number, then 3 and 2,706,150.3333 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 | 8,118,451 | |
| -1 | -8,118,451 |
Let's try dividing by 4:
8,118,451 ÷ 4 = 2,029,612.75
If the quotient is a whole number, then 4 and 2,029,612.75 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 | 8,118,451 | |
| -1 | 8,118,451 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 47 | 383 | 451 | 517 | 1,927 | 4,213 | 15,703 | 18,001 | 21,197 | 172,733 | 198,011 | 738,041 | 8,118,451 |
| -1 | -11 | -41 | -47 | -383 | -451 | -517 | -1,927 | -4,213 | -15,703 | -18,001 | -21,197 | -172,733 | -198,011 | -738,041 | -8,118,451 |
