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 355,005,469, 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 | 355,005,469 | |
| -1 | -355,005,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,005,469.
Example:
1 x 355,005,469 = 355,005,469
and
-1 x -355,005,469 = 355,005,469
Notice both answers equal 355,005,469
With that explanation out of the way, let's continue. Next, we take the number 355,005,469 and divide it by 2:
355,005,469 ÷ 2 = 177,502,734.5
If the quotient is a whole number, then 2 and 177,502,734.5 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 | 355,005,469 | |
| -1 | -355,005,469 |
Now, we try dividing 355,005,469 by 3:
355,005,469 ÷ 3 = 118,335,156.3333
If the quotient is a whole number, then 3 and 118,335,156.3333 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 | 355,005,469 | |
| -1 | -355,005,469 |
Let's try dividing by 4:
355,005,469 ÷ 4 = 88,751,367.25
If the quotient is a whole number, then 4 and 88,751,367.25 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 | 355,005,469 | |
| -1 | 355,005,469 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 787 | 4,957 | 5,509 | 10,231 | 34,699 | 64,441 | 71,617 | 451,087 | 3,901,159 | 27,308,113 | 50,715,067 | 355,005,469 |
| -1 | -7 | -13 | -91 | -787 | -4,957 | -5,509 | -10,231 | -34,699 | -64,441 | -71,617 | -451,087 | -3,901,159 | -27,308,113 | -50,715,067 | -355,005,469 |
