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 105,133,651, 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 | 105,133,651 | |
| -1 | -105,133,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,133,651.
Example:
1 x 105,133,651 = 105,133,651
and
-1 x -105,133,651 = 105,133,651
Notice both answers equal 105,133,651
With that explanation out of the way, let's continue. Next, we take the number 105,133,651 and divide it by 2:
105,133,651 ÷ 2 = 52,566,825.5
If the quotient is a whole number, then 2 and 52,566,825.5 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 | 105,133,651 | |
| -1 | -105,133,651 |
Now, we try dividing 105,133,651 by 3:
105,133,651 ÷ 3 = 35,044,550.3333
If the quotient is a whole number, then 3 and 35,044,550.3333 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 | 105,133,651 | |
| -1 | -105,133,651 |
Let's try dividing by 4:
105,133,651 ÷ 4 = 26,283,412.75
If the quotient is a whole number, then 4 and 26,283,412.75 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 | 105,133,651 | |
| -1 | 105,133,651 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 283 | 511 | 727 | 1,981 | 5,089 | 20,659 | 53,071 | 144,613 | 205,741 | 371,497 | 1,440,187 | 15,019,093 | 105,133,651 |
| -1 | -7 | -73 | -283 | -511 | -727 | -1,981 | -5,089 | -20,659 | -53,071 | -144,613 | -205,741 | -371,497 | -1,440,187 | -15,019,093 | -105,133,651 |
