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 1,924,349, 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 | 1,924,349 | |
| -1 | -1,924,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,924,349.
Example:
1 x 1,924,349 = 1,924,349
and
-1 x -1,924,349 = 1,924,349
Notice both answers equal 1,924,349
With that explanation out of the way, let's continue. Next, we take the number 1,924,349 and divide it by 2:
1,924,349 ÷ 2 = 962,174.5
If the quotient is a whole number, then 2 and 962,174.5 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 | 1,924,349 | |
| -1 | -1,924,349 |
Now, we try dividing 1,924,349 by 3:
1,924,349 ÷ 3 = 641,449.6667
If the quotient is a whole number, then 3 and 641,449.6667 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 | 1,924,349 | |
| -1 | -1,924,349 |
Let's try dividing by 4:
1,924,349 ÷ 4 = 481,087.25
If the quotient is a whole number, then 4 and 481,087.25 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 | 1,924,349 | |
| -1 | 1,924,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 103 | 119 | 157 | 721 | 1,099 | 1,751 | 2,669 | 12,257 | 16,171 | 18,683 | 113,197 | 274,907 | 1,924,349 |
| -1 | -7 | -17 | -103 | -119 | -157 | -721 | -1,099 | -1,751 | -2,669 | -12,257 | -16,171 | -18,683 | -113,197 | -274,907 | -1,924,349 |
