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 7,684,645, 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 | 7,684,645 | |
| -1 | -7,684,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,684,645.
Example:
1 x 7,684,645 = 7,684,645
and
-1 x -7,684,645 = 7,684,645
Notice both answers equal 7,684,645
With that explanation out of the way, let's continue. Next, we take the number 7,684,645 and divide it by 2:
7,684,645 ÷ 2 = 3,842,322.5
If the quotient is a whole number, then 2 and 3,842,322.5 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 | 7,684,645 | |
| -1 | -7,684,645 |
Now, we try dividing 7,684,645 by 3:
7,684,645 ÷ 3 = 2,561,548.3333
If the quotient is a whole number, then 3 and 2,561,548.3333 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 | 7,684,645 | |
| -1 | -7,684,645 |
Let's try dividing by 4:
7,684,645 ÷ 4 = 1,921,161.25
If the quotient is a whole number, then 4 and 1,921,161.25 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 | 7,684,645 | |
| -1 | 7,684,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 3,517 | 17,585 | 66,823 | 80,891 | 334,115 | 404,455 | 1,536,929 | 7,684,645 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -3,517 | -17,585 | -66,823 | -80,891 | -334,115 | -404,455 | -1,536,929 | -7,684,645 |
