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 3,628,765, 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 | 3,628,765 | |
| -1 | -3,628,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,628,765.
Example:
1 x 3,628,765 = 3,628,765
and
-1 x -3,628,765 = 3,628,765
Notice both answers equal 3,628,765
With that explanation out of the way, let's continue. Next, we take the number 3,628,765 and divide it by 2:
3,628,765 ÷ 2 = 1,814,382.5
If the quotient is a whole number, then 2 and 1,814,382.5 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 | 3,628,765 | |
| -1 | -3,628,765 |
Now, we try dividing 3,628,765 by 3:
3,628,765 ÷ 3 = 1,209,588.3333
If the quotient is a whole number, then 3 and 1,209,588.3333 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 | 3,628,765 | |
| -1 | -3,628,765 |
Let's try dividing by 4:
3,628,765 ÷ 4 = 907,191.25
If the quotient is a whole number, then 4 and 907,191.25 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 | 3,628,765 | |
| -1 | 3,628,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 199 | 521 | 995 | 1,393 | 2,605 | 3,647 | 6,965 | 18,235 | 103,679 | 518,395 | 725,753 | 3,628,765 |
| -1 | -5 | -7 | -35 | -199 | -521 | -995 | -1,393 | -2,605 | -3,647 | -6,965 | -18,235 | -103,679 | -518,395 | -725,753 | -3,628,765 |
