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 19,234,601, 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 | 19,234,601 | |
| -1 | -19,234,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,234,601.
Example:
1 x 19,234,601 = 19,234,601
and
-1 x -19,234,601 = 19,234,601
Notice both answers equal 19,234,601
With that explanation out of the way, let's continue. Next, we take the number 19,234,601 and divide it by 2:
19,234,601 ÷ 2 = 9,617,300.5
If the quotient is a whole number, then 2 and 9,617,300.5 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 | 19,234,601 | |
| -1 | -19,234,601 |
Now, we try dividing 19,234,601 by 3:
19,234,601 ÷ 3 = 6,411,533.6667
If the quotient is a whole number, then 3 and 6,411,533.6667 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 | 19,234,601 | |
| -1 | -19,234,601 |
Let's try dividing by 4:
19,234,601 ÷ 4 = 4,808,650.25
If the quotient is a whole number, then 4 and 4,808,650.25 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 | 19,234,601 | |
| -1 | 19,234,601 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 53 | 509 | 713 | 1,219 | 1,643 | 11,707 | 15,779 | 26,977 | 37,789 | 362,917 | 620,471 | 836,287 | 19,234,601 |
| -1 | -23 | -31 | -53 | -509 | -713 | -1,219 | -1,643 | -11,707 | -15,779 | -26,977 | -37,789 | -362,917 | -620,471 | -836,287 | -19,234,601 |
