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 1,227,395, 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 | 1,227,395 | |
| -1 | -1,227,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,227,395.
Example:
1 x 1,227,395 = 1,227,395
and
-1 x -1,227,395 = 1,227,395
Notice both answers equal 1,227,395
With that explanation out of the way, let's continue. Next, we take the number 1,227,395 and divide it by 2:
1,227,395 ÷ 2 = 613,697.5
If the quotient is a whole number, then 2 and 613,697.5 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 | 1,227,395 | |
| -1 | -1,227,395 |
Now, we try dividing 1,227,395 by 3:
1,227,395 ÷ 3 = 409,131.6667
If the quotient is a whole number, then 3 and 409,131.6667 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 | 1,227,395 | |
| -1 | -1,227,395 |
Let's try dividing by 4:
1,227,395 ÷ 4 = 306,848.75
If the quotient is a whole number, then 4 and 306,848.75 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 | 1,227,395 | |
| -1 | 1,227,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 821 | 1,495 | 4,105 | 10,673 | 18,883 | 53,365 | 94,415 | 245,479 | 1,227,395 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -821 | -1,495 | -4,105 | -10,673 | -18,883 | -53,365 | -94,415 | -245,479 | -1,227,395 |
