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 19,176,101, 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 | 19,176,101 | |
| -1 | -19,176,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,176,101.
Example:
1 x 19,176,101 = 19,176,101
and
-1 x -19,176,101 = 19,176,101
Notice both answers equal 19,176,101
With that explanation out of the way, let's continue. Next, we take the number 19,176,101 and divide it by 2:
19,176,101 ÷ 2 = 9,588,050.5
If the quotient is a whole number, then 2 and 9,588,050.5 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 | 19,176,101 | |
| -1 | -19,176,101 |
Now, we try dividing 19,176,101 by 3:
19,176,101 ÷ 3 = 6,392,033.6667
If the quotient is a whole number, then 3 and 6,392,033.6667 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 | 19,176,101 | |
| -1 | -19,176,101 |
Let's try dividing by 4:
19,176,101 ÷ 4 = 4,794,025.25
If the quotient is a whole number, then 4 and 4,794,025.25 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 | 19,176,101 | |
| -1 | 19,176,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 49 | 259 | 343 | 1,511 | 1,813 | 10,577 | 12,691 | 55,907 | 74,039 | 391,349 | 518,273 | 2,739,443 | 19,176,101 |
| -1 | -7 | -37 | -49 | -259 | -343 | -1,511 | -1,813 | -10,577 | -12,691 | -55,907 | -74,039 | -391,349 | -518,273 | -2,739,443 | -19,176,101 |
