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 353,200,019, 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 | 353,200,019 | |
| -1 | -353,200,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,200,019.
Example:
1 x 353,200,019 = 353,200,019
and
-1 x -353,200,019 = 353,200,019
Notice both answers equal 353,200,019
With that explanation out of the way, let's continue. Next, we take the number 353,200,019 and divide it by 2:
353,200,019 ÷ 2 = 176,600,009.5
If the quotient is a whole number, then 2 and 176,600,009.5 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 | 353,200,019 | |
| -1 | -353,200,019 |
Now, we try dividing 353,200,019 by 3:
353,200,019 ÷ 3 = 117,733,339.6667
If the quotient is a whole number, then 3 and 117,733,339.6667 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 | 353,200,019 | |
| -1 | -353,200,019 |
Let's try dividing by 4:
353,200,019 ÷ 4 = 88,300,004.75
If the quotient is a whole number, then 4 and 88,300,004.75 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 | 353,200,019 | |
| -1 | 353,200,019 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 59 | 899 | 1,711 | 1,829 | 6,659 | 53,041 | 193,111 | 206,429 | 392,881 | 5,986,441 | 11,393,549 | 12,179,311 | 353,200,019 |
| -1 | -29 | -31 | -59 | -899 | -1,711 | -1,829 | -6,659 | -53,041 | -193,111 | -206,429 | -392,881 | -5,986,441 | -11,393,549 | -12,179,311 | -353,200,019 |
