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 2,912,375, 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 | 2,912,375 | |
| -1 | -2,912,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,912,375.
Example:
1 x 2,912,375 = 2,912,375
and
-1 x -2,912,375 = 2,912,375
Notice both answers equal 2,912,375
With that explanation out of the way, let's continue. Next, we take the number 2,912,375 and divide it by 2:
2,912,375 ÷ 2 = 1,456,187.5
If the quotient is a whole number, then 2 and 1,456,187.5 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 | 2,912,375 | |
| -1 | -2,912,375 |
Now, we try dividing 2,912,375 by 3:
2,912,375 ÷ 3 = 970,791.6667
If the quotient is a whole number, then 3 and 970,791.6667 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 | 2,912,375 | |
| -1 | -2,912,375 |
Let's try dividing by 4:
2,912,375 ÷ 4 = 728,093.75
If the quotient is a whole number, then 4 and 728,093.75 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 | 2,912,375 | |
| -1 | 2,912,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 125 | 575 | 1,013 | 2,875 | 5,065 | 23,299 | 25,325 | 116,495 | 126,625 | 582,475 | 2,912,375 |
| -1 | -5 | -23 | -25 | -115 | -125 | -575 | -1,013 | -2,875 | -5,065 | -23,299 | -25,325 | -116,495 | -126,625 | -582,475 | -2,912,375 |
