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 47,456,357, 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 | 47,456,357 | |
| -1 | -47,456,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,456,357.
Example:
1 x 47,456,357 = 47,456,357
and
-1 x -47,456,357 = 47,456,357
Notice both answers equal 47,456,357
With that explanation out of the way, let's continue. Next, we take the number 47,456,357 and divide it by 2:
47,456,357 ÷ 2 = 23,728,178.5
If the quotient is a whole number, then 2 and 23,728,178.5 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 | 47,456,357 | |
| -1 | -47,456,357 |
Now, we try dividing 47,456,357 by 3:
47,456,357 ÷ 3 = 15,818,785.6667
If the quotient is a whole number, then 3 and 15,818,785.6667 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 | 47,456,357 | |
| -1 | -47,456,357 |
Let's try dividing by 4:
47,456,357 ÷ 4 = 11,864,089.25
If the quotient is a whole number, then 4 and 11,864,089.25 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 | 47,456,357 | |
| -1 | 47,456,357 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 229 | 247 | 839 | 2,977 | 4,351 | 10,907 | 15,941 | 56,563 | 192,131 | 207,233 | 2,497,703 | 3,650,489 | 47,456,357 |
| -1 | -13 | -19 | -229 | -247 | -839 | -2,977 | -4,351 | -10,907 | -15,941 | -56,563 | -192,131 | -207,233 | -2,497,703 | -3,650,489 | -47,456,357 |
