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 403,110,455, 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 | 403,110,455 | |
| -1 | -403,110,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,110,455.
Example:
1 x 403,110,455 = 403,110,455
and
-1 x -403,110,455 = 403,110,455
Notice both answers equal 403,110,455
With that explanation out of the way, let's continue. Next, we take the number 403,110,455 and divide it by 2:
403,110,455 ÷ 2 = 201,555,227.5
If the quotient is a whole number, then 2 and 201,555,227.5 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 | 403,110,455 | |
| -1 | -403,110,455 |
Now, we try dividing 403,110,455 by 3:
403,110,455 ÷ 3 = 134,370,151.6667
If the quotient is a whole number, then 3 and 134,370,151.6667 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 | 403,110,455 | |
| -1 | -403,110,455 |
Let's try dividing by 4:
403,110,455 ÷ 4 = 100,777,613.75
If the quotient is a whole number, then 4 and 100,777,613.75 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 | 403,110,455 | |
| -1 | 403,110,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 887 | 4,435 | 8,263 | 9,757 | 41,315 | 48,785 | 90,893 | 454,465 | 7,329,281 | 36,646,405 | 80,622,091 | 403,110,455 |
| -1 | -5 | -11 | -55 | -887 | -4,435 | -8,263 | -9,757 | -41,315 | -48,785 | -90,893 | -454,465 | -7,329,281 | -36,646,405 | -80,622,091 | -403,110,455 |
