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 340,124,239, 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 | 340,124,239 | |
| -1 | -340,124,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,124,239.
Example:
1 x 340,124,239 = 340,124,239
and
-1 x -340,124,239 = 340,124,239
Notice both answers equal 340,124,239
With that explanation out of the way, let's continue. Next, we take the number 340,124,239 and divide it by 2:
340,124,239 ÷ 2 = 170,062,119.5
If the quotient is a whole number, then 2 and 170,062,119.5 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 | 340,124,239 | |
| -1 | -340,124,239 |
Now, we try dividing 340,124,239 by 3:
340,124,239 ÷ 3 = 113,374,746.3333
If the quotient is a whole number, then 3 and 113,374,746.3333 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 | 340,124,239 | |
| -1 | -340,124,239 |
Let's try dividing by 4:
340,124,239 ÷ 4 = 85,031,059.75
If the quotient is a whole number, then 4 and 85,031,059.75 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 | 340,124,239 | |
| -1 | 340,124,239 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 49 | 91 | 259 | 481 | 637 | 1,813 | 3,367 | 14,431 | 23,569 | 101,017 | 187,603 | 533,947 | 707,119 | 1,313,221 | 3,737,629 | 6,941,311 | 9,192,547 | 26,163,403 | 48,589,177 | 340,124,239 |
| -1 | -7 | -13 | -37 | -49 | -91 | -259 | -481 | -637 | -1,813 | -3,367 | -14,431 | -23,569 | -101,017 | -187,603 | -533,947 | -707,119 | -1,313,221 | -3,737,629 | -6,941,311 | -9,192,547 | -26,163,403 | -48,589,177 | -340,124,239 |
