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 3,451,255, 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 | 3,451,255 | |
| -1 | -3,451,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,451,255.
Example:
1 x 3,451,255 = 3,451,255
and
-1 x -3,451,255 = 3,451,255
Notice both answers equal 3,451,255
With that explanation out of the way, let's continue. Next, we take the number 3,451,255 and divide it by 2:
3,451,255 ÷ 2 = 1,725,627.5
If the quotient is a whole number, then 2 and 1,725,627.5 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 | 3,451,255 | |
| -1 | -3,451,255 |
Now, we try dividing 3,451,255 by 3:
3,451,255 ÷ 3 = 1,150,418.3333
If the quotient is a whole number, then 3 and 1,150,418.3333 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 | 3,451,255 | |
| -1 | -3,451,255 |
Let's try dividing by 4:
3,451,255 ÷ 4 = 862,813.75
If the quotient is a whole number, then 4 and 862,813.75 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 | 3,451,255 | |
| -1 | 3,451,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 2,137 | 10,685 | 36,329 | 40,603 | 181,645 | 203,015 | 690,251 | 3,451,255 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -2,137 | -10,685 | -36,329 | -40,603 | -181,645 | -203,015 | -690,251 | -3,451,255 |
