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 10,644,361, 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 | 10,644,361 | |
| -1 | -10,644,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,644,361.
Example:
1 x 10,644,361 = 10,644,361
and
-1 x -10,644,361 = 10,644,361
Notice both answers equal 10,644,361
With that explanation out of the way, let's continue. Next, we take the number 10,644,361 and divide it by 2:
10,644,361 ÷ 2 = 5,322,180.5
If the quotient is a whole number, then 2 and 5,322,180.5 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 | 10,644,361 | |
| -1 | -10,644,361 |
Now, we try dividing 10,644,361 by 3:
10,644,361 ÷ 3 = 3,548,120.3333
If the quotient is a whole number, then 3 and 3,548,120.3333 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 | 10,644,361 | |
| -1 | -10,644,361 |
Let's try dividing by 4:
10,644,361 ÷ 4 = 2,661,090.25
If the quotient is a whole number, then 4 and 2,661,090.25 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 | 10,644,361 | |
| -1 | 10,644,361 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 53 | 91 | 371 | 689 | 2,207 | 4,823 | 15,449 | 28,691 | 116,971 | 200,837 | 818,797 | 1,520,623 | 10,644,361 |
| -1 | -7 | -13 | -53 | -91 | -371 | -689 | -2,207 | -4,823 | -15,449 | -28,691 | -116,971 | -200,837 | -818,797 | -1,520,623 | -10,644,361 |
