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 42,512,375, 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 | 42,512,375 | |
| -1 | -42,512,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,512,375.
Example:
1 x 42,512,375 = 42,512,375
and
-1 x -42,512,375 = 42,512,375
Notice both answers equal 42,512,375
With that explanation out of the way, let's continue. Next, we take the number 42,512,375 and divide it by 2:
42,512,375 ÷ 2 = 21,256,187.5
If the quotient is a whole number, then 2 and 21,256,187.5 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 | 42,512,375 | |
| -1 | -42,512,375 |
Now, we try dividing 42,512,375 by 3:
42,512,375 ÷ 3 = 14,170,791.6667
If the quotient is a whole number, then 3 and 14,170,791.6667 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 | 42,512,375 | |
| -1 | -42,512,375 |
Let's try dividing by 4:
42,512,375 ÷ 4 = 10,628,093.75
If the quotient is a whole number, then 4 and 10,628,093.75 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 | 42,512,375 | |
| -1 | 42,512,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 181 | 905 | 1,879 | 4,525 | 9,395 | 22,625 | 46,975 | 234,875 | 340,099 | 1,700,495 | 8,502,475 | 42,512,375 |
| -1 | -5 | -25 | -125 | -181 | -905 | -1,879 | -4,525 | -9,395 | -22,625 | -46,975 | -234,875 | -340,099 | -1,700,495 | -8,502,475 | -42,512,375 |
