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 1,254,395, 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 | 1,254,395 | |
| -1 | -1,254,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,254,395.
Example:
1 x 1,254,395 = 1,254,395
and
-1 x -1,254,395 = 1,254,395
Notice both answers equal 1,254,395
With that explanation out of the way, let's continue. Next, we take the number 1,254,395 and divide it by 2:
1,254,395 ÷ 2 = 627,197.5
If the quotient is a whole number, then 2 and 627,197.5 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 | 1,254,395 | |
| -1 | -1,254,395 |
Now, we try dividing 1,254,395 by 3:
1,254,395 ÷ 3 = 418,131.6667
If the quotient is a whole number, then 3 and 418,131.6667 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 | 1,254,395 | |
| -1 | -1,254,395 |
Let's try dividing by 4:
1,254,395 ÷ 4 = 313,598.75
If the quotient is a whole number, then 4 and 313,598.75 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 | 1,254,395 | |
| -1 | 1,254,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 41 | 145 | 205 | 211 | 1,055 | 1,189 | 5,945 | 6,119 | 8,651 | 30,595 | 43,255 | 250,879 | 1,254,395 |
| -1 | -5 | -29 | -41 | -145 | -205 | -211 | -1,055 | -1,189 | -5,945 | -6,119 | -8,651 | -30,595 | -43,255 | -250,879 | -1,254,395 |
