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 3,102,043, 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 | 3,102,043 | |
| -1 | -3,102,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,102,043.
Example:
1 x 3,102,043 = 3,102,043
and
-1 x -3,102,043 = 3,102,043
Notice both answers equal 3,102,043
With that explanation out of the way, let's continue. Next, we take the number 3,102,043 and divide it by 2:
3,102,043 ÷ 2 = 1,551,021.5
If the quotient is a whole number, then 2 and 1,551,021.5 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 | 3,102,043 | |
| -1 | -3,102,043 |
Now, we try dividing 3,102,043 by 3:
3,102,043 ÷ 3 = 1,034,014.3333
If the quotient is a whole number, then 3 and 1,034,014.3333 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 | 3,102,043 | |
| -1 | -3,102,043 |
Let's try dividing by 4:
3,102,043 ÷ 4 = 775,510.75
If the quotient is a whole number, then 4 and 775,510.75 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 | 3,102,043 | |
| -1 | 3,102,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 37 | 49 | 59 | 203 | 259 | 413 | 1,073 | 1,421 | 1,711 | 1,813 | 2,183 | 2,891 | 7,511 | 11,977 | 15,281 | 52,577 | 63,307 | 83,839 | 106,967 | 443,149 | 3,102,043 |
| -1 | -7 | -29 | -37 | -49 | -59 | -203 | -259 | -413 | -1,073 | -1,421 | -1,711 | -1,813 | -2,183 | -2,891 | -7,511 | -11,977 | -15,281 | -52,577 | -63,307 | -83,839 | -106,967 | -443,149 | -3,102,043 |
