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 3,038,735, 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 | 3,038,735 | |
| -1 | -3,038,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,038,735.
Example:
1 x 3,038,735 = 3,038,735
and
-1 x -3,038,735 = 3,038,735
Notice both answers equal 3,038,735
With that explanation out of the way, let's continue. Next, we take the number 3,038,735 and divide it by 2:
3,038,735 ÷ 2 = 1,519,367.5
If the quotient is a whole number, then 2 and 1,519,367.5 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 | 3,038,735 | |
| -1 | -3,038,735 |
Now, we try dividing 3,038,735 by 3:
3,038,735 ÷ 3 = 1,012,911.6667
If the quotient is a whole number, then 3 and 1,012,911.6667 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 | 3,038,735 | |
| -1 | -3,038,735 |
Let's try dividing by 4:
3,038,735 ÷ 4 = 759,683.75
If the quotient is a whole number, then 4 and 759,683.75 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 | 3,038,735 | |
| -1 | 3,038,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 79 | 157 | 245 | 395 | 553 | 785 | 1,099 | 2,765 | 3,871 | 5,495 | 7,693 | 12,403 | 19,355 | 38,465 | 62,015 | 86,821 | 434,105 | 607,747 | 3,038,735 |
| -1 | -5 | -7 | -35 | -49 | -79 | -157 | -245 | -395 | -553 | -785 | -1,099 | -2,765 | -3,871 | -5,495 | -7,693 | -12,403 | -19,355 | -38,465 | -62,015 | -86,821 | -434,105 | -607,747 | -3,038,735 |
