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 10,665,455, 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 | 10,665,455 | |
| -1 | -10,665,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,665,455.
Example:
1 x 10,665,455 = 10,665,455
and
-1 x -10,665,455 = 10,665,455
Notice both answers equal 10,665,455
With that explanation out of the way, let's continue. Next, we take the number 10,665,455 and divide it by 2:
10,665,455 ÷ 2 = 5,332,727.5
If the quotient is a whole number, then 2 and 5,332,727.5 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 | 10,665,455 | |
| -1 | -10,665,455 |
Now, we try dividing 10,665,455 by 3:
10,665,455 ÷ 3 = 3,555,151.6667
If the quotient is a whole number, then 3 and 3,555,151.6667 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 | 10,665,455 | |
| -1 | -10,665,455 |
Let's try dividing by 4:
10,665,455 ÷ 4 = 2,666,363.75
If the quotient is a whole number, then 4 and 2,666,363.75 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 | 10,665,455 | |
| -1 | 10,665,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 167 | 241 | 265 | 835 | 1,205 | 8,851 | 12,773 | 40,247 | 44,255 | 63,865 | 201,235 | 2,133,091 | 10,665,455 |
| -1 | -5 | -53 | -167 | -241 | -265 | -835 | -1,205 | -8,851 | -12,773 | -40,247 | -44,255 | -63,865 | -201,235 | -2,133,091 | -10,665,455 |
