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 10,649,605, 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 | 10,649,605 | |
| -1 | -10,649,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,649,605.
Example:
1 x 10,649,605 = 10,649,605
and
-1 x -10,649,605 = 10,649,605
Notice both answers equal 10,649,605
With that explanation out of the way, let's continue. Next, we take the number 10,649,605 and divide it by 2:
10,649,605 ÷ 2 = 5,324,802.5
If the quotient is a whole number, then 2 and 5,324,802.5 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 | 10,649,605 | |
| -1 | -10,649,605 |
Now, we try dividing 10,649,605 by 3:
10,649,605 ÷ 3 = 3,549,868.3333
If the quotient is a whole number, then 3 and 3,549,868.3333 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 | 10,649,605 | |
| -1 | -10,649,605 |
Let's try dividing by 4:
10,649,605 ÷ 4 = 2,662,401.25
If the quotient is a whole number, then 4 and 2,662,401.25 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 | 10,649,605 | |
| -1 | 10,649,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 163 | 179 | 365 | 815 | 895 | 11,899 | 13,067 | 29,177 | 59,495 | 65,335 | 145,885 | 2,129,921 | 10,649,605 |
| -1 | -5 | -73 | -163 | -179 | -365 | -815 | -895 | -11,899 | -13,067 | -29,177 | -59,495 | -65,335 | -145,885 | -2,129,921 | -10,649,605 |
