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 3,787,355, 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 | 3,787,355 | |
| -1 | -3,787,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,787,355.
Example:
1 x 3,787,355 = 3,787,355
and
-1 x -3,787,355 = 3,787,355
Notice both answers equal 3,787,355
With that explanation out of the way, let's continue. Next, we take the number 3,787,355 and divide it by 2:
3,787,355 ÷ 2 = 1,893,677.5
If the quotient is a whole number, then 2 and 1,893,677.5 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 | 3,787,355 | |
| -1 | -3,787,355 |
Now, we try dividing 3,787,355 by 3:
3,787,355 ÷ 3 = 1,262,451.6667
If the quotient is a whole number, then 3 and 1,262,451.6667 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 | 3,787,355 | |
| -1 | -3,787,355 |
Let's try dividing by 4:
3,787,355 ÷ 4 = 946,838.75
If the quotient is a whole number, then 4 and 946,838.75 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 | 3,787,355 | |
| -1 | 3,787,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 5,297 | 26,485 | 58,267 | 68,861 | 291,335 | 344,305 | 757,471 | 3,787,355 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -5,297 | -26,485 | -58,267 | -68,861 | -291,335 | -344,305 | -757,471 | -3,787,355 |
