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 1,273,895, 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 | 1,273,895 | |
| -1 | -1,273,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,273,895.
Example:
1 x 1,273,895 = 1,273,895
and
-1 x -1,273,895 = 1,273,895
Notice both answers equal 1,273,895
With that explanation out of the way, let's continue. Next, we take the number 1,273,895 and divide it by 2:
1,273,895 ÷ 2 = 636,947.5
If the quotient is a whole number, then 2 and 636,947.5 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 | 1,273,895 | |
| -1 | -1,273,895 |
Now, we try dividing 1,273,895 by 3:
1,273,895 ÷ 3 = 424,631.6667
If the quotient is a whole number, then 3 and 424,631.6667 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 | 1,273,895 | |
| -1 | -1,273,895 |
Let's try dividing by 4:
1,273,895 ÷ 4 = 318,473.75
If the quotient is a whole number, then 4 and 318,473.75 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 | 1,273,895 | |
| -1 | 1,273,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 2,141 | 10,705 | 14,987 | 36,397 | 74,935 | 181,985 | 254,779 | 1,273,895 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -2,141 | -10,705 | -14,987 | -36,397 | -74,935 | -181,985 | -254,779 | -1,273,895 |
