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 5,132,071, 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 | 5,132,071 | |
| -1 | -5,132,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,132,071.
Example:
1 x 5,132,071 = 5,132,071
and
-1 x -5,132,071 = 5,132,071
Notice both answers equal 5,132,071
With that explanation out of the way, let's continue. Next, we take the number 5,132,071 and divide it by 2:
5,132,071 ÷ 2 = 2,566,035.5
If the quotient is a whole number, then 2 and 2,566,035.5 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 | 5,132,071 | |
| -1 | -5,132,071 |
Now, we try dividing 5,132,071 by 3:
5,132,071 ÷ 3 = 1,710,690.3333
If the quotient is a whole number, then 3 and 1,710,690.3333 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 | 5,132,071 | |
| -1 | -5,132,071 |
Let's try dividing by 4:
5,132,071 ÷ 4 = 1,283,017.75
If the quotient is a whole number, then 4 and 1,283,017.75 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 | 5,132,071 | |
| -1 | 5,132,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 47 | 133 | 329 | 821 | 893 | 5,747 | 6,251 | 15,599 | 38,587 | 109,193 | 270,109 | 733,153 | 5,132,071 |
| -1 | -7 | -19 | -47 | -133 | -329 | -821 | -893 | -5,747 | -6,251 | -15,599 | -38,587 | -109,193 | -270,109 | -733,153 | -5,132,071 |
