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 7,832,923, 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 | 7,832,923 | |
| -1 | -7,832,923 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,832,923.
Example:
1 x 7,832,923 = 7,832,923
and
-1 x -7,832,923 = 7,832,923
Notice both answers equal 7,832,923
With that explanation out of the way, let's continue. Next, we take the number 7,832,923 and divide it by 2:
7,832,923 ÷ 2 = 3,916,461.5
If the quotient is a whole number, then 2 and 3,916,461.5 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 | 7,832,923 | |
| -1 | -7,832,923 |
Now, we try dividing 7,832,923 by 3:
7,832,923 ÷ 3 = 2,610,974.3333
If the quotient is a whole number, then 3 and 2,610,974.3333 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 | 7,832,923 | |
| -1 | -7,832,923 |
Let's try dividing by 4:
7,832,923 ÷ 4 = 1,958,230.75
If the quotient is a whole number, then 4 and 1,958,230.75 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 | 7,832,923 | |
| -1 | 7,832,923 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 53 | 301 | 371 | 491 | 2,279 | 3,437 | 15,953 | 21,113 | 26,023 | 147,791 | 182,161 | 1,118,989 | 7,832,923 |
| -1 | -7 | -43 | -53 | -301 | -371 | -491 | -2,279 | -3,437 | -15,953 | -21,113 | -26,023 | -147,791 | -182,161 | -1,118,989 | -7,832,923 |
