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 10,342,127, 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 | 10,342,127 | |
| -1 | -10,342,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,342,127.
Example:
1 x 10,342,127 = 10,342,127
and
-1 x -10,342,127 = 10,342,127
Notice both answers equal 10,342,127
With that explanation out of the way, let's continue. Next, we take the number 10,342,127 and divide it by 2:
10,342,127 ÷ 2 = 5,171,063.5
If the quotient is a whole number, then 2 and 5,171,063.5 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 | 10,342,127 | |
| -1 | -10,342,127 |
Now, we try dividing 10,342,127 by 3:
10,342,127 ÷ 3 = 3,447,375.6667
If the quotient is a whole number, then 3 and 3,447,375.6667 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 | 10,342,127 | |
| -1 | -10,342,127 |
Let's try dividing by 4:
10,342,127 ÷ 4 = 2,585,531.75
If the quotient is a whole number, then 4 and 2,585,531.75 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 | 10,342,127 | |
| -1 | 10,342,127 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 79 | 103 | 1,271 | 2,449 | 3,193 | 3,239 | 4,223 | 8,137 | 100,409 | 130,913 | 252,247 | 333,617 | 10,342,127 |
| -1 | -31 | -41 | -79 | -103 | -1,271 | -2,449 | -3,193 | -3,239 | -4,223 | -8,137 | -100,409 | -130,913 | -252,247 | -333,617 | -10,342,127 |
