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 19,536,179, 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 | 19,536,179 | |
| -1 | -19,536,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,536,179.
Example:
1 x 19,536,179 = 19,536,179
and
-1 x -19,536,179 = 19,536,179
Notice both answers equal 19,536,179
With that explanation out of the way, let's continue. Next, we take the number 19,536,179 and divide it by 2:
19,536,179 ÷ 2 = 9,768,089.5
If the quotient is a whole number, then 2 and 9,768,089.5 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 | 19,536,179 | |
| -1 | -19,536,179 |
Now, we try dividing 19,536,179 by 3:
19,536,179 ÷ 3 = 6,512,059.6667
If the quotient is a whole number, then 3 and 6,512,059.6667 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 | 19,536,179 | |
| -1 | -19,536,179 |
Let's try dividing by 4:
19,536,179 ÷ 4 = 4,884,044.75
If the quotient is a whole number, then 4 and 4,884,044.75 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 | 19,536,179 | |
| -1 | 19,536,179 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 109 | 221 | 811 | 1,417 | 1,853 | 10,543 | 13,787 | 24,089 | 88,399 | 179,231 | 1,149,187 | 1,502,783 | 19,536,179 |
| -1 | -13 | -17 | -109 | -221 | -811 | -1,417 | -1,853 | -10,543 | -13,787 | -24,089 | -88,399 | -179,231 | -1,149,187 | -1,502,783 | -19,536,179 |
