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 48,212,047, 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 | 48,212,047 | |
| -1 | -48,212,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,212,047.
Example:
1 x 48,212,047 = 48,212,047
and
-1 x -48,212,047 = 48,212,047
Notice both answers equal 48,212,047
With that explanation out of the way, let's continue. Next, we take the number 48,212,047 and divide it by 2:
48,212,047 ÷ 2 = 24,106,023.5
If the quotient is a whole number, then 2 and 24,106,023.5 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 | 48,212,047 | |
| -1 | -48,212,047 |
Now, we try dividing 48,212,047 by 3:
48,212,047 ÷ 3 = 16,070,682.3333
If the quotient is a whole number, then 3 and 16,070,682.3333 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 | 48,212,047 | |
| -1 | -48,212,047 |
Let's try dividing by 4:
48,212,047 ÷ 4 = 12,053,011.75
If the quotient is a whole number, then 4 and 12,053,011.75 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 | 48,212,047 | |
| -1 | 48,212,047 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 101 | 503 | 949 | 1,313 | 6,539 | 7,373 | 36,719 | 50,803 | 95,849 | 477,347 | 660,439 | 3,708,619 | 48,212,047 |
| -1 | -13 | -73 | -101 | -503 | -949 | -1,313 | -6,539 | -7,373 | -36,719 | -50,803 | -95,849 | -477,347 | -660,439 | -3,708,619 | -48,212,047 |
