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 28,848,715, 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 | 28,848,715 | |
| -1 | -28,848,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,848,715.
Example:
1 x 28,848,715 = 28,848,715
and
-1 x -28,848,715 = 28,848,715
Notice both answers equal 28,848,715
With that explanation out of the way, let's continue. Next, we take the number 28,848,715 and divide it by 2:
28,848,715 ÷ 2 = 14,424,357.5
If the quotient is a whole number, then 2 and 14,424,357.5 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 | 28,848,715 | |
| -1 | -28,848,715 |
Now, we try dividing 28,848,715 by 3:
28,848,715 ÷ 3 = 9,616,238.3333
If the quotient is a whole number, then 3 and 9,616,238.3333 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 | 28,848,715 | |
| -1 | -28,848,715 |
Let's try dividing by 4:
28,848,715 ÷ 4 = 7,212,178.75
If the quotient is a whole number, then 4 and 7,212,178.75 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 | 28,848,715 | |
| -1 | 28,848,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 1,295 | 22,277 | 111,385 | 155,939 | 779,695 | 824,249 | 4,121,245 | 5,769,743 | 28,848,715 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -1,295 | -22,277 | -111,385 | -155,939 | -779,695 | -824,249 | -4,121,245 | -5,769,743 | -28,848,715 |
