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 8,630,845, 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 | 8,630,845 | |
| -1 | -8,630,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,630,845.
Example:
1 x 8,630,845 = 8,630,845
and
-1 x -8,630,845 = 8,630,845
Notice both answers equal 8,630,845
With that explanation out of the way, let's continue. Next, we take the number 8,630,845 and divide it by 2:
8,630,845 ÷ 2 = 4,315,422.5
If the quotient is a whole number, then 2 and 4,315,422.5 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 | 8,630,845 | |
| -1 | -8,630,845 |
Now, we try dividing 8,630,845 by 3:
8,630,845 ÷ 3 = 2,876,948.3333
If the quotient is a whole number, then 3 and 2,876,948.3333 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 | 8,630,845 | |
| -1 | -8,630,845 |
Let's try dividing by 4:
8,630,845 ÷ 4 = 2,157,711.25
If the quotient is a whole number, then 4 and 2,157,711.25 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 | 8,630,845 | |
| -1 | 8,630,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 893 | 1,933 | 4,465 | 9,665 | 36,727 | 90,851 | 183,635 | 454,255 | 1,726,169 | 8,630,845 |
| -1 | -5 | -19 | -47 | -95 | -235 | -893 | -1,933 | -4,465 | -9,665 | -36,727 | -90,851 | -183,635 | -454,255 | -1,726,169 | -8,630,845 |
