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 2,038,435, 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 | 2,038,435 | |
| -1 | -2,038,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,038,435.
Example:
1 x 2,038,435 = 2,038,435
and
-1 x -2,038,435 = 2,038,435
Notice both answers equal 2,038,435
With that explanation out of the way, let's continue. Next, we take the number 2,038,435 and divide it by 2:
2,038,435 ÷ 2 = 1,019,217.5
If the quotient is a whole number, then 2 and 1,019,217.5 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 | 2,038,435 | |
| -1 | -2,038,435 |
Now, we try dividing 2,038,435 by 3:
2,038,435 ÷ 3 = 679,478.3333
If the quotient is a whole number, then 3 and 679,478.3333 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 | 2,038,435 | |
| -1 | -2,038,435 |
Let's try dividing by 4:
2,038,435 ÷ 4 = 509,608.75
If the quotient is a whole number, then 4 and 509,608.75 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 | 2,038,435 | |
| -1 | 2,038,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 139 | 419 | 695 | 973 | 2,095 | 2,933 | 4,865 | 14,665 | 58,241 | 291,205 | 407,687 | 2,038,435 |
| -1 | -5 | -7 | -35 | -139 | -419 | -695 | -973 | -2,095 | -2,933 | -4,865 | -14,665 | -58,241 | -291,205 | -407,687 | -2,038,435 |
