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 3,776,839, 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 | 3,776,839 | |
| -1 | -3,776,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,776,839.
Example:
1 x 3,776,839 = 3,776,839
and
-1 x -3,776,839 = 3,776,839
Notice both answers equal 3,776,839
With that explanation out of the way, let's continue. Next, we take the number 3,776,839 and divide it by 2:
3,776,839 ÷ 2 = 1,888,419.5
If the quotient is a whole number, then 2 and 1,888,419.5 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 | 3,776,839 | |
| -1 | -3,776,839 |
Now, we try dividing 3,776,839 by 3:
3,776,839 ÷ 3 = 1,258,946.3333
If the quotient is a whole number, then 3 and 1,258,946.3333 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 | 3,776,839 | |
| -1 | -3,776,839 |
Let's try dividing by 4:
3,776,839 ÷ 4 = 944,209.75
If the quotient is a whole number, then 4 and 944,209.75 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 | 3,776,839 | |
| -1 | 3,776,839 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 187 | 209 | 323 | 1,063 | 3,553 | 11,693 | 18,071 | 20,197 | 198,781 | 222,167 | 343,349 | 3,776,839 |
| -1 | -11 | -17 | -19 | -187 | -209 | -323 | -1,063 | -3,553 | -11,693 | -18,071 | -20,197 | -198,781 | -222,167 | -343,349 | -3,776,839 |
