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 10,040,455, 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 | 10,040,455 | |
| -1 | -10,040,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,040,455.
Example:
1 x 10,040,455 = 10,040,455
and
-1 x -10,040,455 = 10,040,455
Notice both answers equal 10,040,455
With that explanation out of the way, let's continue. Next, we take the number 10,040,455 and divide it by 2:
10,040,455 ÷ 2 = 5,020,227.5
If the quotient is a whole number, then 2 and 5,020,227.5 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 | 10,040,455 | |
| -1 | -10,040,455 |
Now, we try dividing 10,040,455 by 3:
10,040,455 ÷ 3 = 3,346,818.3333
If the quotient is a whole number, then 3 and 3,346,818.3333 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 | 10,040,455 | |
| -1 | -10,040,455 |
Let's try dividing by 4:
10,040,455 ÷ 4 = 2,510,113.75
If the quotient is a whole number, then 4 and 2,510,113.75 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 | 10,040,455 | |
| -1 | 10,040,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 6,217 | 31,085 | 105,689 | 118,123 | 528,445 | 590,615 | 2,008,091 | 10,040,455 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -6,217 | -31,085 | -105,689 | -118,123 | -528,445 | -590,615 | -2,008,091 | -10,040,455 |
