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 352,121,119, 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 | 352,121,119 | |
| -1 | -352,121,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,121,119.
Example:
1 x 352,121,119 = 352,121,119
and
-1 x -352,121,119 = 352,121,119
Notice both answers equal 352,121,119
With that explanation out of the way, let's continue. Next, we take the number 352,121,119 and divide it by 2:
352,121,119 ÷ 2 = 176,060,559.5
If the quotient is a whole number, then 2 and 176,060,559.5 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 | 352,121,119 | |
| -1 | -352,121,119 |
Now, we try dividing 352,121,119 by 3:
352,121,119 ÷ 3 = 117,373,706.3333
If the quotient is a whole number, then 3 and 117,373,706.3333 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 | 352,121,119 | |
| -1 | -352,121,119 |
Let's try dividing by 4:
352,121,119 ÷ 4 = 88,030,279.75
If the quotient is a whole number, then 4 and 88,030,279.75 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 | 352,121,119 | |
| -1 | 352,121,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 37 | 119 | 259 | 629 | 4,403 | 79,973 | 559,811 | 1,359,541 | 2,959,001 | 9,516,787 | 20,713,007 | 50,303,017 | 352,121,119 |
| -1 | -7 | -17 | -37 | -119 | -259 | -629 | -4,403 | -79,973 | -559,811 | -1,359,541 | -2,959,001 | -9,516,787 | -20,713,007 | -50,303,017 | -352,121,119 |
