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 47,428,885, 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 | 47,428,885 | |
| -1 | -47,428,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,428,885.
Example:
1 x 47,428,885 = 47,428,885
and
-1 x -47,428,885 = 47,428,885
Notice both answers equal 47,428,885
With that explanation out of the way, let's continue. Next, we take the number 47,428,885 and divide it by 2:
47,428,885 ÷ 2 = 23,714,442.5
If the quotient is a whole number, then 2 and 23,714,442.5 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 | 47,428,885 | |
| -1 | -47,428,885 |
Now, we try dividing 47,428,885 by 3:
47,428,885 ÷ 3 = 15,809,628.3333
If the quotient is a whole number, then 3 and 15,809,628.3333 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 | 47,428,885 | |
| -1 | -47,428,885 |
Let's try dividing by 4:
47,428,885 ÷ 4 = 11,857,221.25
If the quotient is a whole number, then 4 and 11,857,221.25 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 | 47,428,885 | |
| -1 | 47,428,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 139 | 695 | 973 | 4,865 | 9,749 | 48,745 | 68,243 | 341,215 | 1,355,111 | 6,775,555 | 9,485,777 | 47,428,885 |
| -1 | -5 | -7 | -35 | -139 | -695 | -973 | -4,865 | -9,749 | -48,745 | -68,243 | -341,215 | -1,355,111 | -6,775,555 | -9,485,777 | -47,428,885 |
