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 3,021,415, 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 | 3,021,415 | |
| -1 | -3,021,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,021,415.
Example:
1 x 3,021,415 = 3,021,415
and
-1 x -3,021,415 = 3,021,415
Notice both answers equal 3,021,415
With that explanation out of the way, let's continue. Next, we take the number 3,021,415 and divide it by 2:
3,021,415 ÷ 2 = 1,510,707.5
If the quotient is a whole number, then 2 and 1,510,707.5 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 | 3,021,415 | |
| -1 | -3,021,415 |
Now, we try dividing 3,021,415 by 3:
3,021,415 ÷ 3 = 1,007,138.3333
If the quotient is a whole number, then 3 and 1,007,138.3333 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 | 3,021,415 | |
| -1 | -3,021,415 |
Let's try dividing by 4:
3,021,415 ÷ 4 = 755,353.75
If the quotient is a whole number, then 4 and 755,353.75 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 | 3,021,415 | |
| -1 | 3,021,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 101 | 155 | 193 | 505 | 965 | 3,131 | 5,983 | 15,655 | 19,493 | 29,915 | 97,465 | 604,283 | 3,021,415 |
| -1 | -5 | -31 | -101 | -155 | -193 | -505 | -965 | -3,131 | -5,983 | -15,655 | -19,493 | -29,915 | -97,465 | -604,283 | -3,021,415 |
