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 120,034,343, 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 | 120,034,343 | |
| -1 | -120,034,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,034,343.
Example:
1 x 120,034,343 = 120,034,343
and
-1 x -120,034,343 = 120,034,343
Notice both answers equal 120,034,343
With that explanation out of the way, let's continue. Next, we take the number 120,034,343 and divide it by 2:
120,034,343 ÷ 2 = 60,017,171.5
If the quotient is a whole number, then 2 and 60,017,171.5 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 | 120,034,343 | |
| -1 | -120,034,343 |
Now, we try dividing 120,034,343 by 3:
120,034,343 ÷ 3 = 40,011,447.6667
If the quotient is a whole number, then 3 and 40,011,447.6667 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 | 120,034,343 | |
| -1 | -120,034,343 |
Let's try dividing by 4:
120,034,343 ÷ 4 = 30,008,585.75
If the quotient is a whole number, then 4 and 30,008,585.75 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 | 120,034,343 | |
| -1 | 120,034,343 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 143 | 209 | 247 | 2,717 | 44,179 | 485,969 | 574,327 | 839,401 | 6,317,597 | 9,233,411 | 10,912,213 | 120,034,343 |
| -1 | -11 | -13 | -19 | -143 | -209 | -247 | -2,717 | -44,179 | -485,969 | -574,327 | -839,401 | -6,317,597 | -9,233,411 | -10,912,213 | -120,034,343 |
