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 1,915,823, 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 | 1,915,823 | |
| -1 | -1,915,823 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,915,823.
Example:
1 x 1,915,823 = 1,915,823
and
-1 x -1,915,823 = 1,915,823
Notice both answers equal 1,915,823
With that explanation out of the way, let's continue. Next, we take the number 1,915,823 and divide it by 2:
1,915,823 ÷ 2 = 957,911.5
If the quotient is a whole number, then 2 and 957,911.5 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 | 1,915,823 | |
| -1 | -1,915,823 |
Now, we try dividing 1,915,823 by 3:
1,915,823 ÷ 3 = 638,607.6667
If the quotient is a whole number, then 3 and 638,607.6667 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 | 1,915,823 | |
| -1 | -1,915,823 |
Let's try dividing by 4:
1,915,823 ÷ 4 = 478,955.75
If the quotient is a whole number, then 4 and 478,955.75 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 | 1,915,823 | |
| -1 | 1,915,823 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 91 | 259 | 481 | 569 | 3,367 | 3,983 | 7,397 | 21,053 | 51,779 | 147,371 | 273,689 | 1,915,823 |
| -1 | -7 | -13 | -37 | -91 | -259 | -481 | -569 | -3,367 | -3,983 | -7,397 | -21,053 | -51,779 | -147,371 | -273,689 | -1,915,823 |
