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 1,292,965, 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 | 1,292,965 | |
| -1 | -1,292,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,292,965.
Example:
1 x 1,292,965 = 1,292,965
and
-1 x -1,292,965 = 1,292,965
Notice both answers equal 1,292,965
With that explanation out of the way, let's continue. Next, we take the number 1,292,965 and divide it by 2:
1,292,965 ÷ 2 = 646,482.5
If the quotient is a whole number, then 2 and 646,482.5 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 | 1,292,965 | |
| -1 | -1,292,965 |
Now, we try dividing 1,292,965 by 3:
1,292,965 ÷ 3 = 430,988.3333
If the quotient is a whole number, then 3 and 430,988.3333 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 | 1,292,965 | |
| -1 | -1,292,965 |
Let's try dividing by 4:
1,292,965 ÷ 4 = 323,241.25
If the quotient is a whole number, then 4 and 323,241.25 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 | 1,292,965 | |
| -1 | 1,292,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 37 | 145 | 185 | 241 | 1,073 | 1,205 | 5,365 | 6,989 | 8,917 | 34,945 | 44,585 | 258,593 | 1,292,965 |
| -1 | -5 | -29 | -37 | -145 | -185 | -241 | -1,073 | -1,205 | -5,365 | -6,989 | -8,917 | -34,945 | -44,585 | -258,593 | -1,292,965 |
