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 1,866,875, 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 | 1,866,875 | |
| -1 | -1,866,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,866,875.
Example:
1 x 1,866,875 = 1,866,875
and
-1 x -1,866,875 = 1,866,875
Notice both answers equal 1,866,875
With that explanation out of the way, let's continue. Next, we take the number 1,866,875 and divide it by 2:
1,866,875 ÷ 2 = 933,437.5
If the quotient is a whole number, then 2 and 933,437.5 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 | 1,866,875 | |
| -1 | -1,866,875 |
Now, we try dividing 1,866,875 by 3:
1,866,875 ÷ 3 = 622,291.6667
If the quotient is a whole number, then 3 and 622,291.6667 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 | 1,866,875 | |
| -1 | -1,866,875 |
Let's try dividing by 4:
1,866,875 ÷ 4 = 466,718.75
If the quotient is a whole number, then 4 and 466,718.75 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 | 1,866,875 | |
| -1 | 1,866,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 103 | 125 | 145 | 515 | 625 | 725 | 2,575 | 2,987 | 3,625 | 12,875 | 14,935 | 18,125 | 64,375 | 74,675 | 373,375 | 1,866,875 |
| -1 | -5 | -25 | -29 | -103 | -125 | -145 | -515 | -625 | -725 | -2,575 | -2,987 | -3,625 | -12,875 | -14,935 | -18,125 | -64,375 | -74,675 | -373,375 | -1,866,875 |
