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 415,522,055, 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 | 415,522,055 | |
| -1 | -415,522,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 415,522,055.
Example:
1 x 415,522,055 = 415,522,055
and
-1 x -415,522,055 = 415,522,055
Notice both answers equal 415,522,055
With that explanation out of the way, let's continue. Next, we take the number 415,522,055 and divide it by 2:
415,522,055 ÷ 2 = 207,761,027.5
If the quotient is a whole number, then 2 and 207,761,027.5 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 | 415,522,055 | |
| -1 | -415,522,055 |
Now, we try dividing 415,522,055 by 3:
415,522,055 ÷ 3 = 138,507,351.6667
If the quotient is a whole number, then 3 and 138,507,351.6667 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 | 415,522,055 | |
| -1 | -415,522,055 |
Let's try dividing by 4:
415,522,055 ÷ 4 = 103,880,513.75
If the quotient is a whole number, then 4 and 103,880,513.75 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 | 415,522,055 | |
| -1 | 415,522,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,087 | 5,435 | 5,881 | 14,131 | 29,405 | 70,655 | 76,453 | 382,265 | 6,392,647 | 31,963,235 | 83,104,411 | 415,522,055 |
| -1 | -5 | -13 | -65 | -1,087 | -5,435 | -5,881 | -14,131 | -29,405 | -70,655 | -76,453 | -382,265 | -6,392,647 | -31,963,235 | -83,104,411 | -415,522,055 |
