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 7,604,215, 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 | 7,604,215 | |
| -1 | -7,604,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,604,215.
Example:
1 x 7,604,215 = 7,604,215
and
-1 x -7,604,215 = 7,604,215
Notice both answers equal 7,604,215
With that explanation out of the way, let's continue. Next, we take the number 7,604,215 and divide it by 2:
7,604,215 ÷ 2 = 3,802,107.5
If the quotient is a whole number, then 2 and 3,802,107.5 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 | 7,604,215 | |
| -1 | -7,604,215 |
Now, we try dividing 7,604,215 by 3:
7,604,215 ÷ 3 = 2,534,738.3333
If the quotient is a whole number, then 3 and 2,534,738.3333 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 | 7,604,215 | |
| -1 | -7,604,215 |
Let's try dividing by 4:
7,604,215 ÷ 4 = 1,901,053.75
If the quotient is a whole number, then 4 and 1,901,053.75 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 | 7,604,215 | |
| -1 | 7,604,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 149 | 173 | 295 | 745 | 865 | 8,791 | 10,207 | 25,777 | 43,955 | 51,035 | 128,885 | 1,520,843 | 7,604,215 |
| -1 | -5 | -59 | -149 | -173 | -295 | -745 | -865 | -8,791 | -10,207 | -25,777 | -43,955 | -51,035 | -128,885 | -1,520,843 | -7,604,215 |
