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 19,206,275, 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 | 19,206,275 | |
| -1 | -19,206,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,206,275.
Example:
1 x 19,206,275 = 19,206,275
and
-1 x -19,206,275 = 19,206,275
Notice both answers equal 19,206,275
With that explanation out of the way, let's continue. Next, we take the number 19,206,275 and divide it by 2:
19,206,275 ÷ 2 = 9,603,137.5
If the quotient is a whole number, then 2 and 9,603,137.5 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 | 19,206,275 | |
| -1 | -19,206,275 |
Now, we try dividing 19,206,275 by 3:
19,206,275 ÷ 3 = 6,402,091.6667
If the quotient is a whole number, then 3 and 6,402,091.6667 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 | 19,206,275 | |
| -1 | -19,206,275 |
Let's try dividing by 4:
19,206,275 ÷ 4 = 4,801,568.75
If the quotient is a whole number, then 4 and 4,801,568.75 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 | 19,206,275 | |
| -1 | 19,206,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 211 | 275 | 331 | 1,055 | 1,655 | 2,321 | 3,641 | 5,275 | 8,275 | 11,605 | 18,205 | 58,025 | 69,841 | 91,025 | 349,205 | 768,251 | 1,746,025 | 3,841,255 | 19,206,275 |
