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 3,780,755, 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 | 3,780,755 | |
| -1 | -3,780,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,780,755.
Example:
1 x 3,780,755 = 3,780,755
and
-1 x -3,780,755 = 3,780,755
Notice both answers equal 3,780,755
With that explanation out of the way, let's continue. Next, we take the number 3,780,755 and divide it by 2:
3,780,755 ÷ 2 = 1,890,377.5
If the quotient is a whole number, then 2 and 1,890,377.5 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 | 3,780,755 | |
| -1 | -3,780,755 |
Now, we try dividing 3,780,755 by 3:
3,780,755 ÷ 3 = 1,260,251.6667
If the quotient is a whole number, then 3 and 1,260,251.6667 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 | 3,780,755 | |
| -1 | -3,780,755 |
Let's try dividing by 4:
3,780,755 ÷ 4 = 945,188.75
If the quotient is a whole number, then 4 and 945,188.75 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 | 3,780,755 | |
| -1 | 3,780,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 1,297 | 2,915 | 6,485 | 14,267 | 68,741 | 71,335 | 343,705 | 756,151 | 3,780,755 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -1,297 | -2,915 | -6,485 | -14,267 | -68,741 | -71,335 | -343,705 | -756,151 | -3,780,755 |
