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 2,493,023, 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 | 2,493,023 | |
| -1 | -2,493,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,493,023.
Example:
1 x 2,493,023 = 2,493,023
and
-1 x -2,493,023 = 2,493,023
Notice both answers equal 2,493,023
With that explanation out of the way, let's continue. Next, we take the number 2,493,023 and divide it by 2:
2,493,023 ÷ 2 = 1,246,511.5
If the quotient is a whole number, then 2 and 1,246,511.5 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 | 2,493,023 | |
| -1 | -2,493,023 |
Now, we try dividing 2,493,023 by 3:
2,493,023 ÷ 3 = 831,007.6667
If the quotient is a whole number, then 3 and 831,007.6667 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 | 2,493,023 | |
| -1 | -2,493,023 |
Let's try dividing by 4:
2,493,023 ÷ 4 = 623,255.75
If the quotient is a whole number, then 4 and 623,255.75 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 | 2,493,023 | |
| -1 | 2,493,023 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 71 | 73 | 481 | 923 | 949 | 2,627 | 2,701 | 5,183 | 34,151 | 35,113 | 67,379 | 191,771 | 2,493,023 |
| -1 | -13 | -37 | -71 | -73 | -481 | -923 | -949 | -2,627 | -2,701 | -5,183 | -34,151 | -35,113 | -67,379 | -191,771 | -2,493,023 |
