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 10,431,043, 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 | 10,431,043 | |
| -1 | -10,431,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,431,043.
Example:
1 x 10,431,043 = 10,431,043
and
-1 x -10,431,043 = 10,431,043
Notice both answers equal 10,431,043
With that explanation out of the way, let's continue. Next, we take the number 10,431,043 and divide it by 2:
10,431,043 ÷ 2 = 5,215,521.5
If the quotient is a whole number, then 2 and 5,215,521.5 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 | 10,431,043 | |
| -1 | -10,431,043 |
Now, we try dividing 10,431,043 by 3:
10,431,043 ÷ 3 = 3,477,014.3333
If the quotient is a whole number, then 3 and 3,477,014.3333 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 | 10,431,043 | |
| -1 | -10,431,043 |
Let's try dividing by 4:
10,431,043 ÷ 4 = 2,607,760.75
If the quotient is a whole number, then 4 and 2,607,760.75 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 | 10,431,043 | |
| -1 | 10,431,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 137 | 149 | 511 | 959 | 1,043 | 10,001 | 10,877 | 20,413 | 70,007 | 76,139 | 142,891 | 1,490,149 | 10,431,043 |
| -1 | -7 | -73 | -137 | -149 | -511 | -959 | -1,043 | -10,001 | -10,877 | -20,413 | -70,007 | -76,139 | -142,891 | -1,490,149 | -10,431,043 |
