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 478,337,405, 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 | 478,337,405 | |
| -1 | -478,337,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 478,337,405.
Example:
1 x 478,337,405 = 478,337,405
and
-1 x -478,337,405 = 478,337,405
Notice both answers equal 478,337,405
With that explanation out of the way, let's continue. Next, we take the number 478,337,405 and divide it by 2:
478,337,405 ÷ 2 = 239,168,702.5
If the quotient is a whole number, then 2 and 239,168,702.5 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 | 478,337,405 | |
| -1 | -478,337,405 |
Now, we try dividing 478,337,405 by 3:
478,337,405 ÷ 3 = 159,445,801.6667
If the quotient is a whole number, then 3 and 159,445,801.6667 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 | 478,337,405 | |
| -1 | -478,337,405 |
Let's try dividing by 4:
478,337,405 ÷ 4 = 119,584,351.25
If the quotient is a whole number, then 4 and 119,584,351.25 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 | 478,337,405 | |
| -1 | 478,337,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 1,051,291 | 5,256,455 | 7,359,037 | 13,666,783 | 36,795,185 | 68,333,915 | 95,667,481 | 478,337,405 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -1,051,291 | -5,256,455 | -7,359,037 | -13,666,783 | -36,795,185 | -68,333,915 | -95,667,481 | -478,337,405 |
