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 8,630,435, 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 | 8,630,435 | |
| -1 | -8,630,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,630,435.
Example:
1 x 8,630,435 = 8,630,435
and
-1 x -8,630,435 = 8,630,435
Notice both answers equal 8,630,435
With that explanation out of the way, let's continue. Next, we take the number 8,630,435 and divide it by 2:
8,630,435 ÷ 2 = 4,315,217.5
If the quotient is a whole number, then 2 and 4,315,217.5 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 | 8,630,435 | |
| -1 | -8,630,435 |
Now, we try dividing 8,630,435 by 3:
8,630,435 ÷ 3 = 2,876,811.6667
If the quotient is a whole number, then 3 and 2,876,811.6667 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 | 8,630,435 | |
| -1 | -8,630,435 |
Let's try dividing by 4:
8,630,435 ÷ 4 = 2,157,608.75
If the quotient is a whole number, then 4 and 2,157,608.75 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 | 8,630,435 | |
| -1 | 8,630,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 2,035 | 4,241 | 21,205 | 46,651 | 156,917 | 233,255 | 784,585 | 1,726,087 | 8,630,435 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -2,035 | -4,241 | -21,205 | -46,651 | -156,917 | -233,255 | -784,585 | -1,726,087 | -8,630,435 |
