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 47,504,137, 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 | 47,504,137 | |
| -1 | -47,504,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,504,137.
Example:
1 x 47,504,137 = 47,504,137
and
-1 x -47,504,137 = 47,504,137
Notice both answers equal 47,504,137
With that explanation out of the way, let's continue. Next, we take the number 47,504,137 and divide it by 2:
47,504,137 ÷ 2 = 23,752,068.5
If the quotient is a whole number, then 2 and 23,752,068.5 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 | 47,504,137 | |
| -1 | -47,504,137 |
Now, we try dividing 47,504,137 by 3:
47,504,137 ÷ 3 = 15,834,712.3333
If the quotient is a whole number, then 3 and 15,834,712.3333 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 | 47,504,137 | |
| -1 | -47,504,137 |
Let's try dividing by 4:
47,504,137 ÷ 4 = 11,876,034.25
If the quotient is a whole number, then 4 and 11,876,034.25 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 | 47,504,137 | |
| -1 | 47,504,137 |
If you did it right, you will end up with this table:
| 1 | 17 | 83 | 131 | 257 | 1,411 | 2,227 | 4,369 | 10,873 | 21,331 | 33,667 | 184,841 | 362,627 | 572,339 | 2,794,361 | 47,504,137 |
| -1 | -17 | -83 | -131 | -257 | -1,411 | -2,227 | -4,369 | -10,873 | -21,331 | -33,667 | -184,841 | -362,627 | -572,339 | -2,794,361 | -47,504,137 |
