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 3,773,909, 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 | 3,773,909 | |
| -1 | -3,773,909 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,773,909.
Example:
1 x 3,773,909 = 3,773,909
and
-1 x -3,773,909 = 3,773,909
Notice both answers equal 3,773,909
With that explanation out of the way, let's continue. Next, we take the number 3,773,909 and divide it by 2:
3,773,909 ÷ 2 = 1,886,954.5
If the quotient is a whole number, then 2 and 1,886,954.5 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 | 3,773,909 | |
| -1 | -3,773,909 |
Now, we try dividing 3,773,909 by 3:
3,773,909 ÷ 3 = 1,257,969.6667
If the quotient is a whole number, then 3 and 1,257,969.6667 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 | 3,773,909 | |
| -1 | -3,773,909 |
Let's try dividing by 4:
3,773,909 ÷ 4 = 943,477.25
If the quotient is a whole number, then 4 and 943,477.25 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 | 3,773,909 | |
| -1 | 3,773,909 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 67 | 79 | 713 | 1,541 | 1,817 | 2,077 | 2,449 | 5,293 | 47,771 | 56,327 | 121,739 | 164,083 | 3,773,909 |
| -1 | -23 | -31 | -67 | -79 | -713 | -1,541 | -1,817 | -2,077 | -2,449 | -5,293 | -47,771 | -56,327 | -121,739 | -164,083 | -3,773,909 |
