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 47,227,457, 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 | 47,227,457 | |
| -1 | -47,227,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,227,457.
Example:
1 x 47,227,457 = 47,227,457
and
-1 x -47,227,457 = 47,227,457
Notice both answers equal 47,227,457
With that explanation out of the way, let's continue. Next, we take the number 47,227,457 and divide it by 2:
47,227,457 ÷ 2 = 23,613,728.5
If the quotient is a whole number, then 2 and 23,613,728.5 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 | 47,227,457 | |
| -1 | -47,227,457 |
Now, we try dividing 47,227,457 by 3:
47,227,457 ÷ 3 = 15,742,485.6667
If the quotient is a whole number, then 3 and 15,742,485.6667 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 | 47,227,457 | |
| -1 | -47,227,457 |
Let's try dividing by 4:
47,227,457 ÷ 4 = 11,806,864.25
If the quotient is a whole number, then 4 and 11,806,864.25 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 | 47,227,457 | |
| -1 | 47,227,457 |
If you did it right, you will end up with this table:
| 1 | 29 | 97 | 103 | 163 | 2,813 | 2,987 | 4,727 | 9,991 | 15,811 | 16,789 | 289,739 | 458,519 | 486,881 | 1,628,533 | 47,227,457 |
| -1 | -29 | -97 | -103 | -163 | -2,813 | -2,987 | -4,727 | -9,991 | -15,811 | -16,789 | -289,739 | -458,519 | -486,881 | -1,628,533 | -47,227,457 |
