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 42,513,407, 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 | 42,513,407 | |
| -1 | -42,513,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,513,407.
Example:
1 x 42,513,407 = 42,513,407
and
-1 x -42,513,407 = 42,513,407
Notice both answers equal 42,513,407
With that explanation out of the way, let's continue. Next, we take the number 42,513,407 and divide it by 2:
42,513,407 ÷ 2 = 21,256,703.5
If the quotient is a whole number, then 2 and 21,256,703.5 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 | 42,513,407 | |
| -1 | -42,513,407 |
Now, we try dividing 42,513,407 by 3:
42,513,407 ÷ 3 = 14,171,135.6667
If the quotient is a whole number, then 3 and 14,171,135.6667 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 | 42,513,407 | |
| -1 | -42,513,407 |
Let's try dividing by 4:
42,513,407 ÷ 4 = 10,628,351.75
If the quotient is a whole number, then 4 and 10,628,351.75 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 | 42,513,407 | |
| -1 | 42,513,407 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 851 | 49,957 | 1,149,011 | 1,848,409 | 42,513,407 |
| -1 | -23 | -37 | -851 | -49,957 | -1,149,011 | -1,848,409 | -42,513,407 |
