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 344,574,377, 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 | 344,574,377 | |
| -1 | -344,574,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 344,574,377.
Example:
1 x 344,574,377 = 344,574,377
and
-1 x -344,574,377 = 344,574,377
Notice both answers equal 344,574,377
With that explanation out of the way, let's continue. Next, we take the number 344,574,377 and divide it by 2:
344,574,377 ÷ 2 = 172,287,188.5
If the quotient is a whole number, then 2 and 172,287,188.5 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 | 344,574,377 | |
| -1 | -344,574,377 |
Now, we try dividing 344,574,377 by 3:
344,574,377 ÷ 3 = 114,858,125.6667
If the quotient is a whole number, then 3 and 114,858,125.6667 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 | 344,574,377 | |
| -1 | -344,574,377 |
Let's try dividing by 4:
344,574,377 ÷ 4 = 86,143,594.25
If the quotient is a whole number, then 4 and 86,143,594.25 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 | 344,574,377 | |
| -1 | 344,574,377 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 37 | 119 | 259 | 629 | 4,403 | 78,259 | 547,813 | 1,330,403 | 2,895,583 | 9,312,821 | 20,269,081 | 49,224,911 | 344,574,377 |
| -1 | -7 | -17 | -37 | -119 | -259 | -629 | -4,403 | -78,259 | -547,813 | -1,330,403 | -2,895,583 | -9,312,821 | -20,269,081 | -49,224,911 | -344,574,377 |
