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 8,621,345, 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 | 8,621,345 | |
| -1 | -8,621,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,621,345.
Example:
1 x 8,621,345 = 8,621,345
and
-1 x -8,621,345 = 8,621,345
Notice both answers equal 8,621,345
With that explanation out of the way, let's continue. Next, we take the number 8,621,345 and divide it by 2:
8,621,345 ÷ 2 = 4,310,672.5
If the quotient is a whole number, then 2 and 4,310,672.5 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 | 8,621,345 | |
| -1 | -8,621,345 |
Now, we try dividing 8,621,345 by 3:
8,621,345 ÷ 3 = 2,873,781.6667
If the quotient is a whole number, then 3 and 2,873,781.6667 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 | 8,621,345 | |
| -1 | -8,621,345 |
Let's try dividing by 4:
8,621,345 ÷ 4 = 2,155,336.25
If the quotient is a whole number, then 4 and 2,155,336.25 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 | 8,621,345 | |
| -1 | 8,621,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 151 | 601 | 755 | 2,869 | 3,005 | 11,419 | 14,345 | 57,095 | 90,751 | 453,755 | 1,724,269 | 8,621,345 |
| -1 | -5 | -19 | -95 | -151 | -601 | -755 | -2,869 | -3,005 | -11,419 | -14,345 | -57,095 | -90,751 | -453,755 | -1,724,269 | -8,621,345 |
