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 12,343,859, 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 | 12,343,859 | |
| -1 | -12,343,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,343,859.
Example:
1 x 12,343,859 = 12,343,859
and
-1 x -12,343,859 = 12,343,859
Notice both answers equal 12,343,859
With that explanation out of the way, let's continue. Next, we take the number 12,343,859 and divide it by 2:
12,343,859 ÷ 2 = 6,171,929.5
If the quotient is a whole number, then 2 and 6,171,929.5 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 | 12,343,859 | |
| -1 | -12,343,859 |
Now, we try dividing 12,343,859 by 3:
12,343,859 ÷ 3 = 4,114,619.6667
If the quotient is a whole number, then 3 and 4,114,619.6667 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 | 12,343,859 | |
| -1 | -12,343,859 |
Let's try dividing by 4:
12,343,859 ÷ 4 = 3,085,964.75
If the quotient is a whole number, then 4 and 3,085,964.75 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 | 12,343,859 | |
| -1 | 12,343,859 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 53 | 341 | 583 | 683 | 1,643 | 7,513 | 18,073 | 21,173 | 36,199 | 232,903 | 398,189 | 1,122,169 | 12,343,859 |
| -1 | -11 | -31 | -53 | -341 | -583 | -683 | -1,643 | -7,513 | -18,073 | -21,173 | -36,199 | -232,903 | -398,189 | -1,122,169 | -12,343,859 |
