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 1,203,923, 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 | 1,203,923 | |
| -1 | -1,203,923 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,203,923.
Example:
1 x 1,203,923 = 1,203,923
and
-1 x -1,203,923 = 1,203,923
Notice both answers equal 1,203,923
With that explanation out of the way, let's continue. Next, we take the number 1,203,923 and divide it by 2:
1,203,923 ÷ 2 = 601,961.5
If the quotient is a whole number, then 2 and 601,961.5 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 | 1,203,923 | |
| -1 | -1,203,923 |
Now, we try dividing 1,203,923 by 3:
1,203,923 ÷ 3 = 401,307.6667
If the quotient is a whole number, then 3 and 401,307.6667 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 | 1,203,923 | |
| -1 | -1,203,923 |
Let's try dividing by 4:
1,203,923 ÷ 4 = 300,980.75
If the quotient is a whole number, then 4 and 300,980.75 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 | 1,203,923 | |
| -1 | 1,203,923 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 67 | 119 | 151 | 469 | 1,057 | 1,139 | 2,567 | 7,973 | 10,117 | 17,969 | 70,819 | 171,989 | 1,203,923 |
| -1 | -7 | -17 | -67 | -119 | -151 | -469 | -1,057 | -1,139 | -2,567 | -7,973 | -10,117 | -17,969 | -70,819 | -171,989 | -1,203,923 |
