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 340,504,121, 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 | 340,504,121 | |
| -1 | -340,504,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,504,121.
Example:
1 x 340,504,121 = 340,504,121
and
-1 x -340,504,121 = 340,504,121
Notice both answers equal 340,504,121
With that explanation out of the way, let's continue. Next, we take the number 340,504,121 and divide it by 2:
340,504,121 ÷ 2 = 170,252,060.5
If the quotient is a whole number, then 2 and 170,252,060.5 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 | 340,504,121 | |
| -1 | -340,504,121 |
Now, we try dividing 340,504,121 by 3:
340,504,121 ÷ 3 = 113,501,373.6667
If the quotient is a whole number, then 3 and 113,501,373.6667 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 | 340,504,121 | |
| -1 | -340,504,121 |
Let's try dividing by 4:
340,504,121 ÷ 4 = 85,126,030.25
If the quotient is a whole number, then 4 and 85,126,030.25 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 | 340,504,121 | |
| -1 | 340,504,121 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 397 | 419 | 2,047 | 9,131 | 9,637 | 35,333 | 37,291 | 166,343 | 812,659 | 857,693 | 3,825,889 | 14,804,527 | 340,504,121 |
| -1 | -23 | -89 | -397 | -419 | -2,047 | -9,131 | -9,637 | -35,333 | -37,291 | -166,343 | -812,659 | -857,693 | -3,825,889 | -14,804,527 | -340,504,121 |
