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 404,516,455, 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 | 404,516,455 | |
| -1 | -404,516,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,516,455.
Example:
1 x 404,516,455 = 404,516,455
and
-1 x -404,516,455 = 404,516,455
Notice both answers equal 404,516,455
With that explanation out of the way, let's continue. Next, we take the number 404,516,455 and divide it by 2:
404,516,455 ÷ 2 = 202,258,227.5
If the quotient is a whole number, then 2 and 202,258,227.5 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 | 404,516,455 | |
| -1 | -404,516,455 |
Now, we try dividing 404,516,455 by 3:
404,516,455 ÷ 3 = 134,838,818.3333
If the quotient is a whole number, then 3 and 134,838,818.3333 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 | 404,516,455 | |
| -1 | -404,516,455 |
Let's try dividing by 4:
404,516,455 ÷ 4 = 101,129,113.75
If the quotient is a whole number, then 4 and 101,129,113.75 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 | 404,516,455 | |
| -1 | 404,516,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 281,893 | 1,409,465 | 1,973,251 | 9,866,255 | 11,557,613 | 57,788,065 | 80,903,291 | 404,516,455 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -281,893 | -1,409,465 | -1,973,251 | -9,866,255 | -11,557,613 | -57,788,065 | -80,903,291 | -404,516,455 |
