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 1,299,625, 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 | 1,299,625 | |
| -1 | -1,299,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,299,625.
Example:
1 x 1,299,625 = 1,299,625
and
-1 x -1,299,625 = 1,299,625
Notice both answers equal 1,299,625
With that explanation out of the way, let's continue. Next, we take the number 1,299,625 and divide it by 2:
1,299,625 ÷ 2 = 649,812.5
If the quotient is a whole number, then 2 and 649,812.5 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 | 1,299,625 | |
| -1 | -1,299,625 |
Now, we try dividing 1,299,625 by 3:
1,299,625 ÷ 3 = 433,208.3333
If the quotient is a whole number, then 3 and 433,208.3333 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 | 1,299,625 | |
| -1 | -1,299,625 |
Let's try dividing by 4:
1,299,625 ÷ 4 = 324,906.25
If the quotient is a whole number, then 4 and 324,906.25 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 | 1,299,625 | |
| -1 | 1,299,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 125 | 185 | 281 | 925 | 1,405 | 4,625 | 7,025 | 10,397 | 35,125 | 51,985 | 259,925 | 1,299,625 |
| -1 | -5 | -25 | -37 | -125 | -185 | -281 | -925 | -1,405 | -4,625 | -7,025 | -10,397 | -35,125 | -51,985 | -259,925 | -1,299,625 |
