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 3,611,785, 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 | 3,611,785 | |
| -1 | -3,611,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,611,785.
Example:
1 x 3,611,785 = 3,611,785
and
-1 x -3,611,785 = 3,611,785
Notice both answers equal 3,611,785
With that explanation out of the way, let's continue. Next, we take the number 3,611,785 and divide it by 2:
3,611,785 ÷ 2 = 1,805,892.5
If the quotient is a whole number, then 2 and 1,805,892.5 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 | 3,611,785 | |
| -1 | -3,611,785 |
Now, we try dividing 3,611,785 by 3:
3,611,785 ÷ 3 = 1,203,928.3333
If the quotient is a whole number, then 3 and 1,203,928.3333 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 | 3,611,785 | |
| -1 | -3,611,785 |
Let's try dividing by 4:
3,611,785 ÷ 4 = 902,946.25
If the quotient is a whole number, then 4 and 902,946.25 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 | 3,611,785 | |
| -1 | 3,611,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 107 | 157 | 215 | 535 | 785 | 4,601 | 6,751 | 16,799 | 23,005 | 33,755 | 83,995 | 722,357 | 3,611,785 |
| -1 | -5 | -43 | -107 | -157 | -215 | -535 | -785 | -4,601 | -6,751 | -16,799 | -23,005 | -33,755 | -83,995 | -722,357 | -3,611,785 |
