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 342,202,105, 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 | 342,202,105 | |
| -1 | -342,202,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,202,105.
Example:
1 x 342,202,105 = 342,202,105
and
-1 x -342,202,105 = 342,202,105
Notice both answers equal 342,202,105
With that explanation out of the way, let's continue. Next, we take the number 342,202,105 and divide it by 2:
342,202,105 ÷ 2 = 171,101,052.5
If the quotient is a whole number, then 2 and 171,101,052.5 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 | 342,202,105 | |
| -1 | -342,202,105 |
Now, we try dividing 342,202,105 by 3:
342,202,105 ÷ 3 = 114,067,368.3333
If the quotient is a whole number, then 3 and 114,067,368.3333 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 | 342,202,105 | |
| -1 | -342,202,105 |
Let's try dividing by 4:
342,202,105 ÷ 4 = 85,550,526.25
If the quotient is a whole number, then 4 and 85,550,526.25 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 | 342,202,105 | |
| -1 | 342,202,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 251 | 1,255 | 1,757 | 8,785 | 38,953 | 194,765 | 272,671 | 1,363,355 | 9,777,203 | 48,886,015 | 68,440,421 | 342,202,105 |
| -1 | -5 | -7 | -35 | -251 | -1,255 | -1,757 | -8,785 | -38,953 | -194,765 | -272,671 | -1,363,355 | -9,777,203 | -48,886,015 | -68,440,421 | -342,202,105 |
