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 8,358,305, 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 | 8,358,305 | |
| -1 | -8,358,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,358,305.
Example:
1 x 8,358,305 = 8,358,305
and
-1 x -8,358,305 = 8,358,305
Notice both answers equal 8,358,305
With that explanation out of the way, let's continue. Next, we take the number 8,358,305 and divide it by 2:
8,358,305 ÷ 2 = 4,179,152.5
If the quotient is a whole number, then 2 and 4,179,152.5 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 | 8,358,305 | |
| -1 | -8,358,305 |
Now, we try dividing 8,358,305 by 3:
8,358,305 ÷ 3 = 2,786,101.6667
If the quotient is a whole number, then 3 and 2,786,101.6667 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 | 8,358,305 | |
| -1 | -8,358,305 |
Let's try dividing by 4:
8,358,305 ÷ 4 = 2,089,576.25
If the quotient is a whole number, then 4 and 2,089,576.25 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 | 8,358,305 | |
| -1 | 8,358,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 107 | 535 | 919 | 1,819 | 4,595 | 9,095 | 15,623 | 78,115 | 98,333 | 491,665 | 1,671,661 | 8,358,305 |
| -1 | -5 | -17 | -85 | -107 | -535 | -919 | -1,819 | -4,595 | -9,095 | -15,623 | -78,115 | -98,333 | -491,665 | -1,671,661 | -8,358,305 |
