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 352,554,215, 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 | 352,554,215 | |
| -1 | -352,554,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,554,215.
Example:
1 x 352,554,215 = 352,554,215
and
-1 x -352,554,215 = 352,554,215
Notice both answers equal 352,554,215
With that explanation out of the way, let's continue. Next, we take the number 352,554,215 and divide it by 2:
352,554,215 ÷ 2 = 176,277,107.5
If the quotient is a whole number, then 2 and 176,277,107.5 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 | 352,554,215 | |
| -1 | -352,554,215 |
Now, we try dividing 352,554,215 by 3:
352,554,215 ÷ 3 = 117,518,071.6667
If the quotient is a whole number, then 3 and 117,518,071.6667 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 | 352,554,215 | |
| -1 | -352,554,215 |
Let's try dividing by 4:
352,554,215 ÷ 4 = 88,138,553.75
If the quotient is a whole number, then 4 and 88,138,553.75 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 | 352,554,215 | |
| -1 | 352,554,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 285,469 | 1,427,345 | 3,711,097 | 5,423,911 | 18,555,485 | 27,119,555 | 70,510,843 | 352,554,215 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -285,469 | -1,427,345 | -3,711,097 | -5,423,911 | -18,555,485 | -27,119,555 | -70,510,843 | -352,554,215 |
