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 8,654,239, 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 | 8,654,239 | |
| -1 | -8,654,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,654,239.
Example:
1 x 8,654,239 = 8,654,239
and
-1 x -8,654,239 = 8,654,239
Notice both answers equal 8,654,239
With that explanation out of the way, let's continue. Next, we take the number 8,654,239 and divide it by 2:
8,654,239 ÷ 2 = 4,327,119.5
If the quotient is a whole number, then 2 and 4,327,119.5 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 | 8,654,239 | |
| -1 | -8,654,239 |
Now, we try dividing 8,654,239 by 3:
8,654,239 ÷ 3 = 2,884,746.3333
If the quotient is a whole number, then 3 and 2,884,746.3333 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 | 8,654,239 | |
| -1 | -8,654,239 |
Let's try dividing by 4:
8,654,239 ÷ 4 = 2,163,559.75
If the quotient is a whole number, then 4 and 2,163,559.75 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 | 8,654,239 | |
| -1 | 8,654,239 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 41 | 341 | 451 | 619 | 1,271 | 6,809 | 13,981 | 19,189 | 25,379 | 211,079 | 279,169 | 786,749 | 8,654,239 |
| -1 | -11 | -31 | -41 | -341 | -451 | -619 | -1,271 | -6,809 | -13,981 | -19,189 | -25,379 | -211,079 | -279,169 | -786,749 | -8,654,239 |
