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 1,226,155, 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 | 1,226,155 | |
| -1 | -1,226,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,226,155.
Example:
1 x 1,226,155 = 1,226,155
and
-1 x -1,226,155 = 1,226,155
Notice both answers equal 1,226,155
With that explanation out of the way, let's continue. Next, we take the number 1,226,155 and divide it by 2:
1,226,155 ÷ 2 = 613,077.5
If the quotient is a whole number, then 2 and 613,077.5 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 | 1,226,155 | |
| -1 | -1,226,155 |
Now, we try dividing 1,226,155 by 3:
1,226,155 ÷ 3 = 408,718.3333
If the quotient is a whole number, then 3 and 408,718.3333 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 | 1,226,155 | |
| -1 | -1,226,155 |
Let's try dividing by 4:
1,226,155 ÷ 4 = 306,538.75
If the quotient is a whole number, then 4 and 306,538.75 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 | 1,226,155 | |
| -1 | 1,226,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 661 | 1,855 | 3,305 | 4,627 | 23,135 | 35,033 | 175,165 | 245,231 | 1,226,155 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -661 | -1,855 | -3,305 | -4,627 | -23,135 | -35,033 | -175,165 | -245,231 | -1,226,155 |
