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 2,043,041, 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 | 2,043,041 | |
| -1 | -2,043,041 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,043,041.
Example:
1 x 2,043,041 = 2,043,041
and
-1 x -2,043,041 = 2,043,041
Notice both answers equal 2,043,041
With that explanation out of the way, let's continue. Next, we take the number 2,043,041 and divide it by 2:
2,043,041 ÷ 2 = 1,021,520.5
If the quotient is a whole number, then 2 and 1,021,520.5 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 | 2,043,041 | |
| -1 | -2,043,041 |
Now, we try dividing 2,043,041 by 3:
2,043,041 ÷ 3 = 681,013.6667
If the quotient is a whole number, then 3 and 681,013.6667 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 | 2,043,041 | |
| -1 | -2,043,041 |
Let's try dividing by 4:
2,043,041 ÷ 4 = 510,760.25
If the quotient is a whole number, then 4 and 510,760.25 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 | 2,043,041 | |
| -1 | 2,043,041 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 157 | 169 | 1,001 | 1,099 | 1,183 | 1,727 | 1,859 | 2,041 | 12,089 | 13,013 | 14,287 | 22,451 | 26,533 | 157,157 | 185,731 | 291,863 | 2,043,041 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -157 | -169 | -1,001 | -1,099 | -1,183 | -1,727 | -1,859 | -2,041 | -12,089 | -13,013 | -14,287 | -22,451 | -26,533 | -157,157 | -185,731 | -291,863 | -2,043,041 |
