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 1,276,015, 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 | 1,276,015 | |
| -1 | -1,276,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,276,015.
Example:
1 x 1,276,015 = 1,276,015
and
-1 x -1,276,015 = 1,276,015
Notice both answers equal 1,276,015
With that explanation out of the way, let's continue. Next, we take the number 1,276,015 and divide it by 2:
1,276,015 ÷ 2 = 638,007.5
If the quotient is a whole number, then 2 and 638,007.5 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 | 1,276,015 | |
| -1 | -1,276,015 |
Now, we try dividing 1,276,015 by 3:
1,276,015 ÷ 3 = 425,338.3333
If the quotient is a whole number, then 3 and 425,338.3333 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 | 1,276,015 | |
| -1 | -1,276,015 |
Let's try dividing by 4:
1,276,015 ÷ 4 = 319,003.75
If the quotient is a whole number, then 4 and 319,003.75 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 | 1,276,015 | |
| -1 | 1,276,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 67 | 293 | 335 | 871 | 1,465 | 3,809 | 4,355 | 19,045 | 19,631 | 98,155 | 255,203 | 1,276,015 |
| -1 | -5 | -13 | -65 | -67 | -293 | -335 | -871 | -1,465 | -3,809 | -4,355 | -19,045 | -19,631 | -98,155 | -255,203 | -1,276,015 |
