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 1,902,875, 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 | 1,902,875 | |
| -1 | -1,902,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,902,875.
Example:
1 x 1,902,875 = 1,902,875
and
-1 x -1,902,875 = 1,902,875
Notice both answers equal 1,902,875
With that explanation out of the way, let's continue. Next, we take the number 1,902,875 and divide it by 2:
1,902,875 ÷ 2 = 951,437.5
If the quotient is a whole number, then 2 and 951,437.5 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 | 1,902,875 | |
| -1 | -1,902,875 |
Now, we try dividing 1,902,875 by 3:
1,902,875 ÷ 3 = 634,291.6667
If the quotient is a whole number, then 3 and 634,291.6667 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 | 1,902,875 | |
| -1 | -1,902,875 |
Let's try dividing by 4:
1,902,875 ÷ 4 = 475,718.75
If the quotient is a whole number, then 4 and 475,718.75 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 | 1,902,875 | |
| -1 | 1,902,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,171 | 1,625 | 5,855 | 15,223 | 29,275 | 76,115 | 146,375 | 380,575 | 1,902,875 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,171 | -1,625 | -5,855 | -15,223 | -29,275 | -76,115 | -146,375 | -380,575 | -1,902,875 |
