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 5,038,523, 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 | 5,038,523 | |
| -1 | -5,038,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,038,523.
Example:
1 x 5,038,523 = 5,038,523
and
-1 x -5,038,523 = 5,038,523
Notice both answers equal 5,038,523
With that explanation out of the way, let's continue. Next, we take the number 5,038,523 and divide it by 2:
5,038,523 ÷ 2 = 2,519,261.5
If the quotient is a whole number, then 2 and 2,519,261.5 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 | 5,038,523 | |
| -1 | -5,038,523 |
Now, we try dividing 5,038,523 by 3:
5,038,523 ÷ 3 = 1,679,507.6667
If the quotient is a whole number, then 3 and 1,679,507.6667 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 | 5,038,523 | |
| -1 | -5,038,523 |
Let's try dividing by 4:
5,038,523 ÷ 4 = 1,259,630.75
If the quotient is a whole number, then 4 and 1,259,630.75 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 | 5,038,523 | |
| -1 | 5,038,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 107 | 217 | 749 | 961 | 1,519 | 3,317 | 5,243 | 6,727 | 23,219 | 47,089 | 102,827 | 162,533 | 719,789 | 5,038,523 |
| -1 | -7 | -31 | -49 | -107 | -217 | -749 | -961 | -1,519 | -3,317 | -5,243 | -6,727 | -23,219 | -47,089 | -102,827 | -162,533 | -719,789 | -5,038,523 |
