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 2,116,675, 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 | 2,116,675 | |
| -1 | -2,116,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,116,675.
Example:
1 x 2,116,675 = 2,116,675
and
-1 x -2,116,675 = 2,116,675
Notice both answers equal 2,116,675
With that explanation out of the way, let's continue. Next, we take the number 2,116,675 and divide it by 2:
2,116,675 ÷ 2 = 1,058,337.5
If the quotient is a whole number, then 2 and 1,058,337.5 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 | 2,116,675 | |
| -1 | -2,116,675 |
Now, we try dividing 2,116,675 by 3:
2,116,675 ÷ 3 = 705,558.3333
If the quotient is a whole number, then 3 and 705,558.3333 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 | 2,116,675 | |
| -1 | -2,116,675 |
Let's try dividing by 4:
2,116,675 ÷ 4 = 529,168.75
If the quotient is a whole number, then 4 and 529,168.75 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 | 2,116,675 | |
| -1 | 2,116,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 43 | 55 | 179 | 215 | 275 | 473 | 895 | 1,075 | 1,969 | 2,365 | 4,475 | 7,697 | 9,845 | 11,825 | 38,485 | 49,225 | 84,667 | 192,425 | 423,335 | 2,116,675 |
| -1 | -5 | -11 | -25 | -43 | -55 | -179 | -215 | -275 | -473 | -895 | -1,075 | -1,969 | -2,365 | -4,475 | -7,697 | -9,845 | -11,825 | -38,485 | -49,225 | -84,667 | -192,425 | -423,335 | -2,116,675 |
