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 48,046,831, 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 | 48,046,831 | |
| -1 | -48,046,831 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,046,831.
Example:
1 x 48,046,831 = 48,046,831
and
-1 x -48,046,831 = 48,046,831
Notice both answers equal 48,046,831
With that explanation out of the way, let's continue. Next, we take the number 48,046,831 and divide it by 2:
48,046,831 ÷ 2 = 24,023,415.5
If the quotient is a whole number, then 2 and 24,023,415.5 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 | 48,046,831 | |
| -1 | -48,046,831 |
Now, we try dividing 48,046,831 by 3:
48,046,831 ÷ 3 = 16,015,610.3333
If the quotient is a whole number, then 3 and 16,015,610.3333 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 | 48,046,831 | |
| -1 | -48,046,831 |
Let's try dividing by 4:
48,046,831 ÷ 4 = 12,011,707.75
If the quotient is a whole number, then 4 and 12,011,707.75 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 | 48,046,831 | |
| -1 | 48,046,831 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 47 | 259 | 329 | 1,739 | 3,947 | 12,173 | 27,629 | 146,039 | 185,509 | 1,022,273 | 1,298,563 | 6,863,833 | 48,046,831 |
| -1 | -7 | -37 | -47 | -259 | -329 | -1,739 | -3,947 | -12,173 | -27,629 | -146,039 | -185,509 | -1,022,273 | -1,298,563 | -6,863,833 | -48,046,831 |
