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 3,615,913, 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 | 3,615,913 | |
| -1 | -3,615,913 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,615,913.
Example:
1 x 3,615,913 = 3,615,913
and
-1 x -3,615,913 = 3,615,913
Notice both answers equal 3,615,913
With that explanation out of the way, let's continue. Next, we take the number 3,615,913 and divide it by 2:
3,615,913 ÷ 2 = 1,807,956.5
If the quotient is a whole number, then 2 and 1,807,956.5 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 | 3,615,913 | |
| -1 | -3,615,913 |
Now, we try dividing 3,615,913 by 3:
3,615,913 ÷ 3 = 1,205,304.3333
If the quotient is a whole number, then 3 and 1,205,304.3333 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 | 3,615,913 | |
| -1 | -3,615,913 |
Let's try dividing by 4:
3,615,913 ÷ 4 = 903,978.25
If the quotient is a whole number, then 4 and 903,978.25 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 | 3,615,913 | |
| -1 | 3,615,913 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 43 | 287 | 293 | 301 | 1,763 | 2,051 | 12,013 | 12,341 | 12,599 | 84,091 | 88,193 | 516,559 | 3,615,913 |
| -1 | -7 | -41 | -43 | -287 | -293 | -301 | -1,763 | -2,051 | -12,013 | -12,341 | -12,599 | -84,091 | -88,193 | -516,559 | -3,615,913 |
