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 47,748,215, 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 | 47,748,215 | |
| -1 | -47,748,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,748,215.
Example:
1 x 47,748,215 = 47,748,215
and
-1 x -47,748,215 = 47,748,215
Notice both answers equal 47,748,215
With that explanation out of the way, let's continue. Next, we take the number 47,748,215 and divide it by 2:
47,748,215 ÷ 2 = 23,874,107.5
If the quotient is a whole number, then 2 and 23,874,107.5 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 | 47,748,215 | |
| -1 | -47,748,215 |
Now, we try dividing 47,748,215 by 3:
47,748,215 ÷ 3 = 15,916,071.6667
If the quotient is a whole number, then 3 and 15,916,071.6667 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 | 47,748,215 | |
| -1 | -47,748,215 |
Let's try dividing by 4:
47,748,215 ÷ 4 = 11,937,053.75
If the quotient is a whole number, then 4 and 11,937,053.75 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 | 47,748,215 | |
| -1 | 47,748,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 107 | 155 | 535 | 2,879 | 3,317 | 14,395 | 16,585 | 89,249 | 308,053 | 446,245 | 1,540,265 | 9,549,643 | 47,748,215 |
| -1 | -5 | -31 | -107 | -155 | -535 | -2,879 | -3,317 | -14,395 | -16,585 | -89,249 | -308,053 | -446,245 | -1,540,265 | -9,549,643 | -47,748,215 |
