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 345,442,055, 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 | 345,442,055 | |
| -1 | -345,442,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,442,055.
Example:
1 x 345,442,055 = 345,442,055
and
-1 x -345,442,055 = 345,442,055
Notice both answers equal 345,442,055
With that explanation out of the way, let's continue. Next, we take the number 345,442,055 and divide it by 2:
345,442,055 ÷ 2 = 172,721,027.5
If the quotient is a whole number, then 2 and 172,721,027.5 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 | 345,442,055 | |
| -1 | -345,442,055 |
Now, we try dividing 345,442,055 by 3:
345,442,055 ÷ 3 = 115,147,351.6667
If the quotient is a whole number, then 3 and 115,147,351.6667 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 | 345,442,055 | |
| -1 | -345,442,055 |
Let's try dividing by 4:
345,442,055 ÷ 4 = 86,360,513.75
If the quotient is a whole number, then 4 and 86,360,513.75 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 | 345,442,055 | |
| -1 | 345,442,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 340,337 | 1,701,685 | 2,382,359 | 9,869,773 | 11,911,795 | 49,348,865 | 69,088,411 | 345,442,055 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -340,337 | -1,701,685 | -2,382,359 | -9,869,773 | -11,911,795 | -49,348,865 | -69,088,411 | -345,442,055 |
