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 340,204,423, 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 | 340,204,423 | |
| -1 | -340,204,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,204,423.
Example:
1 x 340,204,423 = 340,204,423
and
-1 x -340,204,423 = 340,204,423
Notice both answers equal 340,204,423
With that explanation out of the way, let's continue. Next, we take the number 340,204,423 and divide it by 2:
340,204,423 ÷ 2 = 170,102,211.5
If the quotient is a whole number, then 2 and 170,102,211.5 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 | 340,204,423 | |
| -1 | -340,204,423 |
Now, we try dividing 340,204,423 by 3:
340,204,423 ÷ 3 = 113,401,474.3333
If the quotient is a whole number, then 3 and 113,401,474.3333 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 | 340,204,423 | |
| -1 | -340,204,423 |
Let's try dividing by 4:
340,204,423 ÷ 4 = 85,051,105.75
If the quotient is a whole number, then 4 and 85,051,105.75 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 | 340,204,423 | |
| -1 | 340,204,423 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 377 | 379 | 2,381 | 4,927 | 10,991 | 30,953 | 69,049 | 142,883 | 897,637 | 902,399 | 11,731,187 | 26,169,571 | 340,204,423 |
| -1 | -13 | -29 | -377 | -379 | -2,381 | -4,927 | -10,991 | -30,953 | -69,049 | -142,883 | -897,637 | -902,399 | -11,731,187 | -26,169,571 | -340,204,423 |
