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 8,078,435, 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 | 8,078,435 | |
| -1 | -8,078,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,078,435.
Example:
1 x 8,078,435 = 8,078,435
and
-1 x -8,078,435 = 8,078,435
Notice both answers equal 8,078,435
With that explanation out of the way, let's continue. Next, we take the number 8,078,435 and divide it by 2:
8,078,435 ÷ 2 = 4,039,217.5
If the quotient is a whole number, then 2 and 4,039,217.5 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 | 8,078,435 | |
| -1 | -8,078,435 |
Now, we try dividing 8,078,435 by 3:
8,078,435 ÷ 3 = 2,692,811.6667
If the quotient is a whole number, then 3 and 2,692,811.6667 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 | 8,078,435 | |
| -1 | -8,078,435 |
Let's try dividing by 4:
8,078,435 ÷ 4 = 2,019,608.75
If the quotient is a whole number, then 4 and 2,019,608.75 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 | 8,078,435 | |
| -1 | 8,078,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 157 | 205 | 251 | 785 | 1,255 | 6,437 | 10,291 | 32,185 | 39,407 | 51,455 | 197,035 | 1,615,687 | 8,078,435 |
| -1 | -5 | -41 | -157 | -205 | -251 | -785 | -1,255 | -6,437 | -10,291 | -32,185 | -39,407 | -51,455 | -197,035 | -1,615,687 | -8,078,435 |
