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 7,392,931, 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 | 7,392,931 | |
| -1 | -7,392,931 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,392,931.
Example:
1 x 7,392,931 = 7,392,931
and
-1 x -7,392,931 = 7,392,931
Notice both answers equal 7,392,931
With that explanation out of the way, let's continue. Next, we take the number 7,392,931 and divide it by 2:
7,392,931 ÷ 2 = 3,696,465.5
If the quotient is a whole number, then 2 and 3,696,465.5 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 | 7,392,931 | |
| -1 | -7,392,931 |
Now, we try dividing 7,392,931 by 3:
7,392,931 ÷ 3 = 2,464,310.3333
If the quotient is a whole number, then 3 and 2,464,310.3333 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 | 7,392,931 | |
| -1 | -7,392,931 |
Let's try dividing by 4:
7,392,931 ÷ 4 = 1,848,232.75
If the quotient is a whole number, then 4 and 1,848,232.75 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 | 7,392,931 | |
| -1 | 7,392,931 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 137 | 593 | 959 | 1,781 | 4,151 | 7,709 | 12,467 | 53,963 | 81,241 | 568,687 | 1,056,133 | 7,392,931 |
| -1 | -7 | -13 | -91 | -137 | -593 | -959 | -1,781 | -4,151 | -7,709 | -12,467 | -53,963 | -81,241 | -568,687 | -1,056,133 | -7,392,931 |
