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 134,342,215, 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 | 134,342,215 | |
| -1 | -134,342,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,342,215.
Example:
1 x 134,342,215 = 134,342,215
and
-1 x -134,342,215 = 134,342,215
Notice both answers equal 134,342,215
With that explanation out of the way, let's continue. Next, we take the number 134,342,215 and divide it by 2:
134,342,215 ÷ 2 = 67,171,107.5
If the quotient is a whole number, then 2 and 67,171,107.5 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 | 134,342,215 | |
| -1 | -134,342,215 |
Now, we try dividing 134,342,215 by 3:
134,342,215 ÷ 3 = 44,780,738.3333
If the quotient is a whole number, then 3 and 44,780,738.3333 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 | 134,342,215 | |
| -1 | -134,342,215 |
Let's try dividing by 4:
134,342,215 ÷ 4 = 33,585,553.75
If the quotient is a whole number, then 4 and 33,585,553.75 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 | 134,342,215 | |
| -1 | 134,342,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 81,667 | 408,335 | 571,669 | 2,858,345 | 3,838,349 | 19,191,745 | 26,868,443 | 134,342,215 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -81,667 | -408,335 | -571,669 | -2,858,345 | -3,838,349 | -19,191,745 | -26,868,443 | -134,342,215 |
