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 10,166,455, 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 | 10,166,455 | |
| -1 | -10,166,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,166,455.
Example:
1 x 10,166,455 = 10,166,455
and
-1 x -10,166,455 = 10,166,455
Notice both answers equal 10,166,455
With that explanation out of the way, let's continue. Next, we take the number 10,166,455 and divide it by 2:
10,166,455 ÷ 2 = 5,083,227.5
If the quotient is a whole number, then 2 and 5,083,227.5 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 | 10,166,455 | |
| -1 | -10,166,455 |
Now, we try dividing 10,166,455 by 3:
10,166,455 ÷ 3 = 3,388,818.3333
If the quotient is a whole number, then 3 and 3,388,818.3333 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 | 10,166,455 | |
| -1 | -10,166,455 |
Let's try dividing by 4:
10,166,455 ÷ 4 = 2,541,613.75
If the quotient is a whole number, then 4 and 2,541,613.75 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 | 10,166,455 | |
| -1 | 10,166,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 229 | 683 | 1,145 | 2,977 | 3,415 | 8,879 | 14,885 | 44,395 | 156,407 | 782,035 | 2,033,291 | 10,166,455 |
| -1 | -5 | -13 | -65 | -229 | -683 | -1,145 | -2,977 | -3,415 | -8,879 | -14,885 | -44,395 | -156,407 | -782,035 | -2,033,291 | -10,166,455 |
