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 8,635,445, 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 | 8,635,445 | |
| -1 | -8,635,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,635,445.
Example:
1 x 8,635,445 = 8,635,445
and
-1 x -8,635,445 = 8,635,445
Notice both answers equal 8,635,445
With that explanation out of the way, let's continue. Next, we take the number 8,635,445 and divide it by 2:
8,635,445 ÷ 2 = 4,317,722.5
If the quotient is a whole number, then 2 and 4,317,722.5 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 | 8,635,445 | |
| -1 | -8,635,445 |
Now, we try dividing 8,635,445 by 3:
8,635,445 ÷ 3 = 2,878,481.6667
If the quotient is a whole number, then 3 and 2,878,481.6667 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 | 8,635,445 | |
| -1 | -8,635,445 |
Let's try dividing by 4:
8,635,445 ÷ 4 = 2,158,861.25
If the quotient is a whole number, then 4 and 2,158,861.25 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 | 8,635,445 | |
| -1 | 8,635,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 18,979 | 94,895 | 132,853 | 246,727 | 664,265 | 1,233,635 | 1,727,089 | 8,635,445 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -18,979 | -94,895 | -132,853 | -246,727 | -664,265 | -1,233,635 | -1,727,089 | -8,635,445 |
