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 7,358,735, 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 | 7,358,735 | |
| -1 | -7,358,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,358,735.
Example:
1 x 7,358,735 = 7,358,735
and
-1 x -7,358,735 = 7,358,735
Notice both answers equal 7,358,735
With that explanation out of the way, let's continue. Next, we take the number 7,358,735 and divide it by 2:
7,358,735 ÷ 2 = 3,679,367.5
If the quotient is a whole number, then 2 and 3,679,367.5 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 | 7,358,735 | |
| -1 | -7,358,735 |
Now, we try dividing 7,358,735 by 3:
7,358,735 ÷ 3 = 2,452,911.6667
If the quotient is a whole number, then 3 and 2,452,911.6667 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 | 7,358,735 | |
| -1 | -7,358,735 |
Let's try dividing by 4:
7,358,735 ÷ 4 = 1,839,683.75
If the quotient is a whole number, then 4 and 1,839,683.75 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 | 7,358,735 | |
| -1 | 7,358,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 61 | 115 | 305 | 1,049 | 1,403 | 5,245 | 7,015 | 24,127 | 63,989 | 120,635 | 319,945 | 1,471,747 | 7,358,735 |
| -1 | -5 | -23 | -61 | -115 | -305 | -1,049 | -1,403 | -5,245 | -7,015 | -24,127 | -63,989 | -120,635 | -319,945 | -1,471,747 | -7,358,735 |
