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 351,350,135, 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 | 351,350,135 | |
| -1 | -351,350,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,350,135.
Example:
1 x 351,350,135 = 351,350,135
and
-1 x -351,350,135 = 351,350,135
Notice both answers equal 351,350,135
With that explanation out of the way, let's continue. Next, we take the number 351,350,135 and divide it by 2:
351,350,135 ÷ 2 = 175,675,067.5
If the quotient is a whole number, then 2 and 175,675,067.5 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 | 351,350,135 | |
| -1 | -351,350,135 |
Now, we try dividing 351,350,135 by 3:
351,350,135 ÷ 3 = 117,116,711.6667
If the quotient is a whole number, then 3 and 117,116,711.6667 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 | 351,350,135 | |
| -1 | -351,350,135 |
Let's try dividing by 4:
351,350,135 ÷ 4 = 87,837,533.75
If the quotient is a whole number, then 4 and 87,837,533.75 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 | 351,350,135 | |
| -1 | 351,350,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 719 | 3,595 | 5,749 | 12,223 | 28,745 | 61,115 | 97,733 | 488,665 | 4,133,531 | 20,667,655 | 70,270,027 | 351,350,135 |
| -1 | -5 | -17 | -85 | -719 | -3,595 | -5,749 | -12,223 | -28,745 | -61,115 | -97,733 | -488,665 | -4,133,531 | -20,667,655 | -70,270,027 | -351,350,135 |
