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 338,248,189, 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 | 338,248,189 | |
| -1 | -338,248,189 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 338,248,189.
Example:
1 x 338,248,189 = 338,248,189
and
-1 x -338,248,189 = 338,248,189
Notice both answers equal 338,248,189
With that explanation out of the way, let's continue. Next, we take the number 338,248,189 and divide it by 2:
338,248,189 ÷ 2 = 169,124,094.5
If the quotient is a whole number, then 2 and 169,124,094.5 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 | 338,248,189 | |
| -1 | -338,248,189 |
Now, we try dividing 338,248,189 by 3:
338,248,189 ÷ 3 = 112,749,396.3333
If the quotient is a whole number, then 3 and 112,749,396.3333 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 | 338,248,189 | |
| -1 | -338,248,189 |
Let's try dividing by 4:
338,248,189 ÷ 4 = 84,562,047.25
If the quotient is a whole number, then 4 and 84,562,047.25 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 | 338,248,189 | |
| -1 | 338,248,189 |
If you did it right, you will end up with this table:
| 1 | 23 | 71 | 103 | 1,633 | 2,011 | 2,369 | 7,313 | 46,253 | 142,781 | 168,199 | 207,133 | 3,283,963 | 4,764,059 | 14,706,443 | 338,248,189 |
| -1 | -23 | -71 | -103 | -1,633 | -2,011 | -2,369 | -7,313 | -46,253 | -142,781 | -168,199 | -207,133 | -3,283,963 | -4,764,059 | -14,706,443 | -338,248,189 |
