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 10,451,105, 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 | 10,451,105 | |
| -1 | -10,451,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,451,105.
Example:
1 x 10,451,105 = 10,451,105
and
-1 x -10,451,105 = 10,451,105
Notice both answers equal 10,451,105
With that explanation out of the way, let's continue. Next, we take the number 10,451,105 and divide it by 2:
10,451,105 ÷ 2 = 5,225,552.5
If the quotient is a whole number, then 2 and 5,225,552.5 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 | 10,451,105 | |
| -1 | -10,451,105 |
Now, we try dividing 10,451,105 by 3:
10,451,105 ÷ 3 = 3,483,701.6667
If the quotient is a whole number, then 3 and 3,483,701.6667 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 | 10,451,105 | |
| -1 | -10,451,105 |
Let's try dividing by 4:
10,451,105 ÷ 4 = 2,612,776.25
If the quotient is a whole number, then 4 and 2,612,776.25 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 | 10,451,105 | |
| -1 | 10,451,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 7,283 | 36,415 | 50,981 | 254,905 | 298,603 | 1,493,015 | 2,090,221 | 10,451,105 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -7,283 | -36,415 | -50,981 | -254,905 | -298,603 | -1,493,015 | -2,090,221 | -10,451,105 |
