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 47,504,135, 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 | 47,504,135 | |
| -1 | -47,504,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,504,135.
Example:
1 x 47,504,135 = 47,504,135
and
-1 x -47,504,135 = 47,504,135
Notice both answers equal 47,504,135
With that explanation out of the way, let's continue. Next, we take the number 47,504,135 and divide it by 2:
47,504,135 ÷ 2 = 23,752,067.5
If the quotient is a whole number, then 2 and 23,752,067.5 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 | 47,504,135 | |
| -1 | -47,504,135 |
Now, we try dividing 47,504,135 by 3:
47,504,135 ÷ 3 = 15,834,711.6667
If the quotient is a whole number, then 3 and 15,834,711.6667 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 | 47,504,135 | |
| -1 | -47,504,135 |
Let's try dividing by 4:
47,504,135 ÷ 4 = 11,876,033.75
If the quotient is a whole number, then 4 and 11,876,033.75 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 | 47,504,135 | |
| -1 | 47,504,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 349 | 1,745 | 2,443 | 3,889 | 12,215 | 19,445 | 27,223 | 136,115 | 1,357,261 | 6,786,305 | 9,500,827 | 47,504,135 |
| -1 | -5 | -7 | -35 | -349 | -1,745 | -2,443 | -3,889 | -12,215 | -19,445 | -27,223 | -136,115 | -1,357,261 | -6,786,305 | -9,500,827 | -47,504,135 |
