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 47,912,395, 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 | 47,912,395 | |
| -1 | -47,912,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,912,395.
Example:
1 x 47,912,395 = 47,912,395
and
-1 x -47,912,395 = 47,912,395
Notice both answers equal 47,912,395
With that explanation out of the way, let's continue. Next, we take the number 47,912,395 and divide it by 2:
47,912,395 ÷ 2 = 23,956,197.5
If the quotient is a whole number, then 2 and 23,956,197.5 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 | 47,912,395 | |
| -1 | -47,912,395 |
Now, we try dividing 47,912,395 by 3:
47,912,395 ÷ 3 = 15,970,798.3333
If the quotient is a whole number, then 3 and 15,970,798.3333 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 | 47,912,395 | |
| -1 | -47,912,395 |
Let's try dividing by 4:
47,912,395 ÷ 4 = 11,978,098.75
If the quotient is a whole number, then 4 and 11,978,098.75 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 | 47,912,395 | |
| -1 | 47,912,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 41 | 95 | 205 | 779 | 3,895 | 12,301 | 61,505 | 233,719 | 504,341 | 1,168,595 | 2,521,705 | 9,582,479 | 47,912,395 |
| -1 | -5 | -19 | -41 | -95 | -205 | -779 | -3,895 | -12,301 | -61,505 | -233,719 | -504,341 | -1,168,595 | -2,521,705 | -9,582,479 | -47,912,395 |
