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 10,627,015, 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 | 10,627,015 | |
| -1 | -10,627,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,627,015.
Example:
1 x 10,627,015 = 10,627,015
and
-1 x -10,627,015 = 10,627,015
Notice both answers equal 10,627,015
With that explanation out of the way, let's continue. Next, we take the number 10,627,015 and divide it by 2:
10,627,015 ÷ 2 = 5,313,507.5
If the quotient is a whole number, then 2 and 5,313,507.5 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 | 10,627,015 | |
| -1 | -10,627,015 |
Now, we try dividing 10,627,015 by 3:
10,627,015 ÷ 3 = 3,542,338.3333
If the quotient is a whole number, then 3 and 3,542,338.3333 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 | 10,627,015 | |
| -1 | -10,627,015 |
Let's try dividing by 4:
10,627,015 ÷ 4 = 2,656,753.75
If the quotient is a whole number, then 4 and 2,656,753.75 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 | 10,627,015 | |
| -1 | 10,627,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 211 | 1,055 | 1,439 | 1,477 | 7,195 | 7,385 | 10,073 | 50,365 | 303,629 | 1,518,145 | 2,125,403 | 10,627,015 |
| -1 | -5 | -7 | -35 | -211 | -1,055 | -1,439 | -1,477 | -7,195 | -7,385 | -10,073 | -50,365 | -303,629 | -1,518,145 | -2,125,403 | -10,627,015 |
