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 1,231,769, 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 | 1,231,769 | |
| -1 | -1,231,769 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,231,769.
Example:
1 x 1,231,769 = 1,231,769
and
-1 x -1,231,769 = 1,231,769
Notice both answers equal 1,231,769
With that explanation out of the way, let's continue. Next, we take the number 1,231,769 and divide it by 2:
1,231,769 ÷ 2 = 615,884.5
If the quotient is a whole number, then 2 and 615,884.5 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 | 1,231,769 | |
| -1 | -1,231,769 |
Now, we try dividing 1,231,769 by 3:
1,231,769 ÷ 3 = 410,589.6667
If the quotient is a whole number, then 3 and 410,589.6667 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 | 1,231,769 | |
| -1 | -1,231,769 |
Let's try dividing by 4:
1,231,769 ÷ 4 = 307,942.25
If the quotient is a whole number, then 4 and 307,942.25 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 | 1,231,769 | |
| -1 | 1,231,769 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 941 | 1,309 | 6,587 | 10,351 | 15,997 | 72,457 | 111,979 | 175,967 | 1,231,769 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -941 | -1,309 | -6,587 | -10,351 | -15,997 | -72,457 | -111,979 | -175,967 | -1,231,769 |
