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 9,725,365, 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 | 9,725,365 | |
| -1 | -9,725,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,725,365.
Example:
1 x 9,725,365 = 9,725,365
and
-1 x -9,725,365 = 9,725,365
Notice both answers equal 9,725,365
With that explanation out of the way, let's continue. Next, we take the number 9,725,365 and divide it by 2:
9,725,365 ÷ 2 = 4,862,682.5
If the quotient is a whole number, then 2 and 4,862,682.5 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 | 9,725,365 | |
| -1 | -9,725,365 |
Now, we try dividing 9,725,365 by 3:
9,725,365 ÷ 3 = 3,241,788.3333
If the quotient is a whole number, then 3 and 3,241,788.3333 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 | 9,725,365 | |
| -1 | -9,725,365 |
Let's try dividing by 4:
9,725,365 ÷ 4 = 2,431,341.25
If the quotient is a whole number, then 4 and 2,431,341.25 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 | 9,725,365 | |
| -1 | 9,725,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 157 | 785 | 953 | 2,041 | 4,765 | 10,205 | 12,389 | 61,945 | 149,621 | 748,105 | 1,945,073 | 9,725,365 |
| -1 | -5 | -13 | -65 | -157 | -785 | -953 | -2,041 | -4,765 | -10,205 | -12,389 | -61,945 | -149,621 | -748,105 | -1,945,073 | -9,725,365 |
