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 3,858,745, 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 | 3,858,745 | |
| -1 | -3,858,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,858,745.
Example:
1 x 3,858,745 = 3,858,745
and
-1 x -3,858,745 = 3,858,745
Notice both answers equal 3,858,745
With that explanation out of the way, let's continue. Next, we take the number 3,858,745 and divide it by 2:
3,858,745 ÷ 2 = 1,929,372.5
If the quotient is a whole number, then 2 and 1,929,372.5 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 | 3,858,745 | |
| -1 | -3,858,745 |
Now, we try dividing 3,858,745 by 3:
3,858,745 ÷ 3 = 1,286,248.3333
If the quotient is a whole number, then 3 and 1,286,248.3333 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 | 3,858,745 | |
| -1 | -3,858,745 |
Let's try dividing by 4:
3,858,745 ÷ 4 = 964,686.25
If the quotient is a whole number, then 4 and 964,686.25 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 | 3,858,745 | |
| -1 | 3,858,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 4,127 | 20,635 | 45,397 | 70,159 | 226,985 | 350,795 | 771,749 | 3,858,745 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -4,127 | -20,635 | -45,397 | -70,159 | -226,985 | -350,795 | -771,749 | -3,858,745 |
