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 3,021,535, 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 | 3,021,535 | |
| -1 | -3,021,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,021,535.
Example:
1 x 3,021,535 = 3,021,535
and
-1 x -3,021,535 = 3,021,535
Notice both answers equal 3,021,535
With that explanation out of the way, let's continue. Next, we take the number 3,021,535 and divide it by 2:
3,021,535 ÷ 2 = 1,510,767.5
If the quotient is a whole number, then 2 and 1,510,767.5 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 | 3,021,535 | |
| -1 | -3,021,535 |
Now, we try dividing 3,021,535 by 3:
3,021,535 ÷ 3 = 1,007,178.3333
If the quotient is a whole number, then 3 and 1,007,178.3333 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 | 3,021,535 | |
| -1 | -3,021,535 |
Let's try dividing by 4:
3,021,535 ÷ 4 = 755,383.75
If the quotient is a whole number, then 4 and 755,383.75 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 | 3,021,535 | |
| -1 | 3,021,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 137 | 401 | 685 | 1,507 | 2,005 | 4,411 | 7,535 | 22,055 | 54,937 | 274,685 | 604,307 | 3,021,535 |
| -1 | -5 | -11 | -55 | -137 | -401 | -685 | -1,507 | -2,005 | -4,411 | -7,535 | -22,055 | -54,937 | -274,685 | -604,307 | -3,021,535 |
