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 424,146,215, 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 | 424,146,215 | |
| -1 | -424,146,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 424,146,215.
Example:
1 x 424,146,215 = 424,146,215
and
-1 x -424,146,215 = 424,146,215
Notice both answers equal 424,146,215
With that explanation out of the way, let's continue. Next, we take the number 424,146,215 and divide it by 2:
424,146,215 ÷ 2 = 212,073,107.5
If the quotient is a whole number, then 2 and 212,073,107.5 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 | 424,146,215 | |
| -1 | -424,146,215 |
Now, we try dividing 424,146,215 by 3:
424,146,215 ÷ 3 = 141,382,071.6667
If the quotient is a whole number, then 3 and 141,382,071.6667 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 | 424,146,215 | |
| -1 | -424,146,215 |
Let's try dividing by 4:
424,146,215 ÷ 4 = 106,036,553.75
If the quotient is a whole number, then 4 and 106,036,553.75 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 | 424,146,215 | |
| -1 | 424,146,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 593 | 2,965 | 7,529 | 11,267 | 37,645 | 56,335 | 143,051 | 715,255 | 4,464,697 | 22,323,485 | 84,829,243 | 424,146,215 |
| -1 | -5 | -19 | -95 | -593 | -2,965 | -7,529 | -11,267 | -37,645 | -56,335 | -143,051 | -715,255 | -4,464,697 | -22,323,485 | -84,829,243 | -424,146,215 |
