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 302,110,123, 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 | 302,110,123 | |
| -1 | -302,110,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,110,123.
Example:
1 x 302,110,123 = 302,110,123
and
-1 x -302,110,123 = 302,110,123
Notice both answers equal 302,110,123
With that explanation out of the way, let's continue. Next, we take the number 302,110,123 and divide it by 2:
302,110,123 ÷ 2 = 151,055,061.5
If the quotient is a whole number, then 2 and 151,055,061.5 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 | 302,110,123 | |
| -1 | -302,110,123 |
Now, we try dividing 302,110,123 by 3:
302,110,123 ÷ 3 = 100,703,374.3333
If the quotient is a whole number, then 3 and 100,703,374.3333 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 | 302,110,123 | |
| -1 | -302,110,123 |
Let's try dividing by 4:
302,110,123 ÷ 4 = 75,527,530.75
If the quotient is a whole number, then 4 and 75,527,530.75 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 | 302,110,123 | |
| -1 | 302,110,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 83 | 371 | 581 | 4,399 | 9,811 | 30,793 | 68,677 | 519,983 | 814,313 | 3,639,881 | 5,700,191 | 43,158,589 | 302,110,123 |
| -1 | -7 | -53 | -83 | -371 | -581 | -4,399 | -9,811 | -30,793 | -68,677 | -519,983 | -814,313 | -3,639,881 | -5,700,191 | -43,158,589 | -302,110,123 |
