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 34,200,413, 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 | 34,200,413 | |
| -1 | -34,200,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,200,413.
Example:
1 x 34,200,413 = 34,200,413
and
-1 x -34,200,413 = 34,200,413
Notice both answers equal 34,200,413
With that explanation out of the way, let's continue. Next, we take the number 34,200,413 and divide it by 2:
34,200,413 ÷ 2 = 17,100,206.5
If the quotient is a whole number, then 2 and 17,100,206.5 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 | 34,200,413 | |
| -1 | -34,200,413 |
Now, we try dividing 34,200,413 by 3:
34,200,413 ÷ 3 = 11,400,137.6667
If the quotient is a whole number, then 3 and 11,400,137.6667 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 | 34,200,413 | |
| -1 | -34,200,413 |
Let's try dividing by 4:
34,200,413 ÷ 4 = 8,550,103.25
If the quotient is a whole number, then 4 and 8,550,103.25 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 | 34,200,413 | |
| -1 | 34,200,413 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 154,753 | 2,011,789 | 2,630,801 | 34,200,413 |
| -1 | -13 | -17 | -221 | -154,753 | -2,011,789 | -2,630,801 | -34,200,413 |
