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 47,423,785, 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 | 47,423,785 | |
| -1 | -47,423,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,423,785.
Example:
1 x 47,423,785 = 47,423,785
and
-1 x -47,423,785 = 47,423,785
Notice both answers equal 47,423,785
With that explanation out of the way, let's continue. Next, we take the number 47,423,785 and divide it by 2:
47,423,785 ÷ 2 = 23,711,892.5
If the quotient is a whole number, then 2 and 23,711,892.5 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 | 47,423,785 | |
| -1 | -47,423,785 |
Now, we try dividing 47,423,785 by 3:
47,423,785 ÷ 3 = 15,807,928.3333
If the quotient is a whole number, then 3 and 15,807,928.3333 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 | 47,423,785 | |
| -1 | -47,423,785 |
Let's try dividing by 4:
47,423,785 ÷ 4 = 11,855,946.25
If the quotient is a whole number, then 4 and 11,855,946.25 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 | 47,423,785 | |
| -1 | 47,423,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 277 | 353 | 485 | 1,385 | 1,765 | 26,869 | 34,241 | 97,781 | 134,345 | 171,205 | 488,905 | 9,484,757 | 47,423,785 |
| -1 | -5 | -97 | -277 | -353 | -485 | -1,385 | -1,765 | -26,869 | -34,241 | -97,781 | -134,345 | -171,205 | -488,905 | -9,484,757 | -47,423,785 |
