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 1,511,875, 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 | 1,511,875 | |
| -1 | -1,511,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,511,875.
Example:
1 x 1,511,875 = 1,511,875
and
-1 x -1,511,875 = 1,511,875
Notice both answers equal 1,511,875
With that explanation out of the way, let's continue. Next, we take the number 1,511,875 and divide it by 2:
1,511,875 ÷ 2 = 755,937.5
If the quotient is a whole number, then 2 and 755,937.5 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 | 1,511,875 | |
| -1 | -1,511,875 |
Now, we try dividing 1,511,875 by 3:
1,511,875 ÷ 3 = 503,958.3333
If the quotient is a whole number, then 3 and 503,958.3333 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 | 1,511,875 | |
| -1 | -1,511,875 |
Let's try dividing by 4:
1,511,875 ÷ 4 = 377,968.75
If the quotient is a whole number, then 4 and 377,968.75 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 | 1,511,875 | |
| -1 | 1,511,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 59 | 125 | 205 | 295 | 625 | 1,025 | 1,475 | 2,419 | 5,125 | 7,375 | 12,095 | 25,625 | 36,875 | 60,475 | 302,375 | 1,511,875 |
| -1 | -5 | -25 | -41 | -59 | -125 | -205 | -295 | -625 | -1,025 | -1,475 | -2,419 | -5,125 | -7,375 | -12,095 | -25,625 | -36,875 | -60,475 | -302,375 | -1,511,875 |
