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 1,261,663, 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 | 1,261,663 | |
| -1 | -1,261,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,261,663.
Example:
1 x 1,261,663 = 1,261,663
and
-1 x -1,261,663 = 1,261,663
Notice both answers equal 1,261,663
With that explanation out of the way, let's continue. Next, we take the number 1,261,663 and divide it by 2:
1,261,663 ÷ 2 = 630,831.5
If the quotient is a whole number, then 2 and 630,831.5 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 | 1,261,663 | |
| -1 | -1,261,663 |
Now, we try dividing 1,261,663 by 3:
1,261,663 ÷ 3 = 420,554.3333
If the quotient is a whole number, then 3 and 420,554.3333 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 | 1,261,663 | |
| -1 | -1,261,663 |
Let's try dividing by 4:
1,261,663 ÷ 4 = 315,415.75
If the quotient is a whole number, then 4 and 315,415.75 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 | 1,261,663 | |
| -1 | 1,261,663 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 43 | 61 | 481 | 559 | 793 | 1,591 | 2,257 | 2,623 | 20,683 | 29,341 | 34,099 | 97,051 | 1,261,663 |
| -1 | -13 | -37 | -43 | -61 | -481 | -559 | -793 | -1,591 | -2,257 | -2,623 | -20,683 | -29,341 | -34,099 | -97,051 | -1,261,663 |
