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 353,220,439, 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 | 353,220,439 | |
| -1 | -353,220,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,220,439.
Example:
1 x 353,220,439 = 353,220,439
and
-1 x -353,220,439 = 353,220,439
Notice both answers equal 353,220,439
With that explanation out of the way, let's continue. Next, we take the number 353,220,439 and divide it by 2:
353,220,439 ÷ 2 = 176,610,219.5
If the quotient is a whole number, then 2 and 176,610,219.5 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 | 353,220,439 | |
| -1 | -353,220,439 |
Now, we try dividing 353,220,439 by 3:
353,220,439 ÷ 3 = 117,740,146.3333
If the quotient is a whole number, then 3 and 117,740,146.3333 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 | 353,220,439 | |
| -1 | -353,220,439 |
Let's try dividing by 4:
353,220,439 ÷ 4 = 88,305,109.75
If the quotient is a whole number, then 4 and 88,305,109.75 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 | 353,220,439 | |
| -1 | 353,220,439 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 61 | 143 | 671 | 793 | 8,723 | 40,493 | 445,423 | 526,409 | 2,470,073 | 5,790,499 | 27,170,803 | 32,110,949 | 353,220,439 |
| -1 | -11 | -13 | -61 | -143 | -671 | -793 | -8,723 | -40,493 | -445,423 | -526,409 | -2,470,073 | -5,790,499 | -27,170,803 | -32,110,949 | -353,220,439 |
