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 337,943,945, 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 | 337,943,945 | |
| -1 | -337,943,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 337,943,945.
Example:
1 x 337,943,945 = 337,943,945
and
-1 x -337,943,945 = 337,943,945
Notice both answers equal 337,943,945
With that explanation out of the way, let's continue. Next, we take the number 337,943,945 and divide it by 2:
337,943,945 ÷ 2 = 168,971,972.5
If the quotient is a whole number, then 2 and 168,971,972.5 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 | 337,943,945 | |
| -1 | -337,943,945 |
Now, we try dividing 337,943,945 by 3:
337,943,945 ÷ 3 = 112,647,981.6667
If the quotient is a whole number, then 3 and 112,647,981.6667 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 | 337,943,945 | |
| -1 | -337,943,945 |
Let's try dividing by 4:
337,943,945 ÷ 4 = 84,485,986.25
If the quotient is a whole number, then 4 and 84,485,986.25 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 | 337,943,945 | |
| -1 | 337,943,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 179 | 895 | 4,117 | 16,417 | 20,585 | 82,085 | 377,591 | 1,887,955 | 2,938,643 | 14,693,215 | 67,588,789 | 337,943,945 |
| -1 | -5 | -23 | -115 | -179 | -895 | -4,117 | -16,417 | -20,585 | -82,085 | -377,591 | -1,887,955 | -2,938,643 | -14,693,215 | -67,588,789 | -337,943,945 |
