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 3,244,615, 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 | 3,244,615 | |
| -1 | -3,244,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,244,615.
Example:
1 x 3,244,615 = 3,244,615
and
-1 x -3,244,615 = 3,244,615
Notice both answers equal 3,244,615
With that explanation out of the way, let's continue. Next, we take the number 3,244,615 and divide it by 2:
3,244,615 ÷ 2 = 1,622,307.5
If the quotient is a whole number, then 2 and 1,622,307.5 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 | 3,244,615 | |
| -1 | -3,244,615 |
Now, we try dividing 3,244,615 by 3:
3,244,615 ÷ 3 = 1,081,538.3333
If the quotient is a whole number, then 3 and 1,081,538.3333 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 | 3,244,615 | |
| -1 | -3,244,615 |
Let's try dividing by 4:
3,244,615 ÷ 4 = 811,153.75
If the quotient is a whole number, then 4 and 811,153.75 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 | 3,244,615 | |
| -1 | 3,244,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 121 | 155 | 173 | 341 | 605 | 865 | 1,705 | 1,903 | 3,751 | 5,363 | 9,515 | 18,755 | 20,933 | 26,815 | 58,993 | 104,665 | 294,965 | 648,923 | 3,244,615 |
| -1 | -5 | -11 | -31 | -55 | -121 | -155 | -173 | -341 | -605 | -865 | -1,705 | -1,903 | -3,751 | -5,363 | -9,515 | -18,755 | -20,933 | -26,815 | -58,993 | -104,665 | -294,965 | -648,923 | -3,244,615 |
