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 9,728,485, 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 | 9,728,485 | |
| -1 | -9,728,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,728,485.
Example:
1 x 9,728,485 = 9,728,485
and
-1 x -9,728,485 = 9,728,485
Notice both answers equal 9,728,485
With that explanation out of the way, let's continue. Next, we take the number 9,728,485 and divide it by 2:
9,728,485 ÷ 2 = 4,864,242.5
If the quotient is a whole number, then 2 and 4,864,242.5 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 | 9,728,485 | |
| -1 | -9,728,485 |
Now, we try dividing 9,728,485 by 3:
9,728,485 ÷ 3 = 3,242,828.3333
If the quotient is a whole number, then 3 and 3,242,828.3333 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 | 9,728,485 | |
| -1 | -9,728,485 |
Let's try dividing by 4:
9,728,485 ÷ 4 = 2,432,121.25
If the quotient is a whole number, then 4 and 2,432,121.25 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 | 9,728,485 | |
| -1 | 9,728,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 169 | 377 | 397 | 845 | 1,885 | 1,985 | 4,901 | 5,161 | 11,513 | 24,505 | 25,805 | 57,565 | 67,093 | 149,669 | 335,465 | 748,345 | 1,945,697 | 9,728,485 |
| -1 | -5 | -13 | -29 | -65 | -145 | -169 | -377 | -397 | -845 | -1,885 | -1,985 | -4,901 | -5,161 | -11,513 | -24,505 | -25,805 | -57,565 | -67,093 | -149,669 | -335,465 | -748,345 | -1,945,697 | -9,728,485 |
