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 1,225,279, 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 | 1,225,279 | |
| -1 | -1,225,279 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,225,279.
Example:
1 x 1,225,279 = 1,225,279
and
-1 x -1,225,279 = 1,225,279
Notice both answers equal 1,225,279
With that explanation out of the way, let's continue. Next, we take the number 1,225,279 and divide it by 2:
1,225,279 ÷ 2 = 612,639.5
If the quotient is a whole number, then 2 and 612,639.5 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 | 1,225,279 | |
| -1 | -1,225,279 |
Now, we try dividing 1,225,279 by 3:
1,225,279 ÷ 3 = 408,426.3333
If the quotient is a whole number, then 3 and 408,426.3333 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 | 1,225,279 | |
| -1 | -1,225,279 |
Let's try dividing by 4:
1,225,279 ÷ 4 = 306,319.75
If the quotient is a whole number, then 4 and 306,319.75 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 | 1,225,279 | |
| -1 | 1,225,279 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 29 | 167 | 253 | 319 | 667 | 1,837 | 3,841 | 4,843 | 7,337 | 42,251 | 53,273 | 111,389 | 1,225,279 |
| -1 | -11 | -23 | -29 | -167 | -253 | -319 | -667 | -1,837 | -3,841 | -4,843 | -7,337 | -42,251 | -53,273 | -111,389 | -1,225,279 |
