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 47,233,145, 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 | 47,233,145 | |
| -1 | -47,233,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,233,145.
Example:
1 x 47,233,145 = 47,233,145
and
-1 x -47,233,145 = 47,233,145
Notice both answers equal 47,233,145
With that explanation out of the way, let's continue. Next, we take the number 47,233,145 and divide it by 2:
47,233,145 ÷ 2 = 23,616,572.5
If the quotient is a whole number, then 2 and 23,616,572.5 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 | 47,233,145 | |
| -1 | -47,233,145 |
Now, we try dividing 47,233,145 by 3:
47,233,145 ÷ 3 = 15,744,381.6667
If the quotient is a whole number, then 3 and 15,744,381.6667 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 | 47,233,145 | |
| -1 | -47,233,145 |
Let's try dividing by 4:
47,233,145 ÷ 4 = 11,808,286.25
If the quotient is a whole number, then 4 and 11,808,286.25 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 | 47,233,145 | |
| -1 | 47,233,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 21,617 | 108,085 | 410,723 | 497,191 | 2,053,615 | 2,485,955 | 9,446,629 | 47,233,145 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -21,617 | -108,085 | -410,723 | -497,191 | -2,053,615 | -2,485,955 | -9,446,629 | -47,233,145 |
