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 3,455,309, 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 | 3,455,309 | |
| -1 | -3,455,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,455,309.
Example:
1 x 3,455,309 = 3,455,309
and
-1 x -3,455,309 = 3,455,309
Notice both answers equal 3,455,309
With that explanation out of the way, let's continue. Next, we take the number 3,455,309 and divide it by 2:
3,455,309 ÷ 2 = 1,727,654.5
If the quotient is a whole number, then 2 and 1,727,654.5 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 | 3,455,309 | |
| -1 | -3,455,309 |
Now, we try dividing 3,455,309 by 3:
3,455,309 ÷ 3 = 1,151,769.6667
If the quotient is a whole number, then 3 and 1,151,769.6667 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 | 3,455,309 | |
| -1 | -3,455,309 |
Let's try dividing by 4:
3,455,309 ÷ 4 = 863,827.25
If the quotient is a whole number, then 4 and 863,827.25 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 | 3,455,309 | |
| -1 | 3,455,309 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 73 | 143 | 331 | 803 | 949 | 3,641 | 4,303 | 10,439 | 24,163 | 47,333 | 265,793 | 314,119 | 3,455,309 |
| -1 | -11 | -13 | -73 | -143 | -331 | -803 | -949 | -3,641 | -4,303 | -10,439 | -24,163 | -47,333 | -265,793 | -314,119 | -3,455,309 |
