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 12,358,199, 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 | 12,358,199 | |
| -1 | -12,358,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,358,199.
Example:
1 x 12,358,199 = 12,358,199
and
-1 x -12,358,199 = 12,358,199
Notice both answers equal 12,358,199
With that explanation out of the way, let's continue. Next, we take the number 12,358,199 and divide it by 2:
12,358,199 ÷ 2 = 6,179,099.5
If the quotient is a whole number, then 2 and 6,179,099.5 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 | 12,358,199 | |
| -1 | -12,358,199 |
Now, we try dividing 12,358,199 by 3:
12,358,199 ÷ 3 = 4,119,399.6667
If the quotient is a whole number, then 3 and 4,119,399.6667 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 | 12,358,199 | |
| -1 | -12,358,199 |
Let's try dividing by 4:
12,358,199 ÷ 4 = 3,089,549.75
If the quotient is a whole number, then 4 and 3,089,549.75 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 | 12,358,199 | |
| -1 | 12,358,199 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 59 | 161 | 413 | 1,301 | 1,357 | 9,107 | 9,499 | 29,923 | 76,759 | 209,461 | 537,313 | 1,765,457 | 12,358,199 |
| -1 | -7 | -23 | -59 | -161 | -413 | -1,301 | -1,357 | -9,107 | -9,499 | -29,923 | -76,759 | -209,461 | -537,313 | -1,765,457 | -12,358,199 |
