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 42,246,215, 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 | 42,246,215 | |
| -1 | -42,246,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,246,215.
Example:
1 x 42,246,215 = 42,246,215
and
-1 x -42,246,215 = 42,246,215
Notice both answers equal 42,246,215
With that explanation out of the way, let's continue. Next, we take the number 42,246,215 and divide it by 2:
42,246,215 ÷ 2 = 21,123,107.5
If the quotient is a whole number, then 2 and 21,123,107.5 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 | 42,246,215 | |
| -1 | -42,246,215 |
Now, we try dividing 42,246,215 by 3:
42,246,215 ÷ 3 = 14,082,071.6667
If the quotient is a whole number, then 3 and 14,082,071.6667 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 | 42,246,215 | |
| -1 | -42,246,215 |
Let's try dividing by 4:
42,246,215 ÷ 4 = 10,561,553.75
If the quotient is a whole number, then 4 and 10,561,553.75 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 | 42,246,215 | |
| -1 | 42,246,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 40,427 | 202,135 | 444,697 | 768,113 | 2,223,485 | 3,840,565 | 8,449,243 | 42,246,215 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -40,427 | -202,135 | -444,697 | -768,113 | -2,223,485 | -3,840,565 | -8,449,243 | -42,246,215 |
