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 19,242,065, 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 | 19,242,065 | |
| -1 | -19,242,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,242,065.
Example:
1 x 19,242,065 = 19,242,065
and
-1 x -19,242,065 = 19,242,065
Notice both answers equal 19,242,065
With that explanation out of the way, let's continue. Next, we take the number 19,242,065 and divide it by 2:
19,242,065 ÷ 2 = 9,621,032.5
If the quotient is a whole number, then 2 and 9,621,032.5 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 | 19,242,065 | |
| -1 | -19,242,065 |
Now, we try dividing 19,242,065 by 3:
19,242,065 ÷ 3 = 6,414,021.6667
If the quotient is a whole number, then 3 and 6,414,021.6667 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 | 19,242,065 | |
| -1 | -19,242,065 |
Let's try dividing by 4:
19,242,065 ÷ 4 = 4,810,516.25
If the quotient is a whole number, then 4 and 4,810,516.25 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 | 19,242,065 | |
| -1 | 19,242,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 71 | 335 | 355 | 809 | 4,045 | 4,757 | 23,785 | 54,203 | 57,439 | 271,015 | 287,195 | 3,848,413 | 19,242,065 |
| -1 | -5 | -67 | -71 | -335 | -355 | -809 | -4,045 | -4,757 | -23,785 | -54,203 | -57,439 | -271,015 | -287,195 | -3,848,413 | -19,242,065 |
