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 3,154,855, 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 | 3,154,855 | |
| -1 | -3,154,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,154,855.
Example:
1 x 3,154,855 = 3,154,855
and
-1 x -3,154,855 = 3,154,855
Notice both answers equal 3,154,855
With that explanation out of the way, let's continue. Next, we take the number 3,154,855 and divide it by 2:
3,154,855 ÷ 2 = 1,577,427.5
If the quotient is a whole number, then 2 and 1,577,427.5 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 | 3,154,855 | |
| -1 | -3,154,855 |
Now, we try dividing 3,154,855 by 3:
3,154,855 ÷ 3 = 1,051,618.3333
If the quotient is a whole number, then 3 and 1,051,618.3333 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 | 3,154,855 | |
| -1 | -3,154,855 |
Let's try dividing by 4:
3,154,855 ÷ 4 = 788,713.75
If the quotient is a whole number, then 4 and 788,713.75 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 | 3,154,855 | |
| -1 | 3,154,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 3,019 | 15,095 | 33,209 | 57,361 | 166,045 | 286,805 | 630,971 | 3,154,855 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -3,019 | -15,095 | -33,209 | -57,361 | -166,045 | -286,805 | -630,971 | -3,154,855 |
