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 3,067,225, 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 | 3,067,225 | |
| -1 | -3,067,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,067,225.
Example:
1 x 3,067,225 = 3,067,225
and
-1 x -3,067,225 = 3,067,225
Notice both answers equal 3,067,225
With that explanation out of the way, let's continue. Next, we take the number 3,067,225 and divide it by 2:
3,067,225 ÷ 2 = 1,533,612.5
If the quotient is a whole number, then 2 and 1,533,612.5 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 | 3,067,225 | |
| -1 | -3,067,225 |
Now, we try dividing 3,067,225 by 3:
3,067,225 ÷ 3 = 1,022,408.3333
If the quotient is a whole number, then 3 and 1,022,408.3333 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 | 3,067,225 | |
| -1 | -3,067,225 |
Let's try dividing by 4:
3,067,225 ÷ 4 = 766,806.25
If the quotient is a whole number, then 4 and 766,806.25 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 | 3,067,225 | |
| -1 | 3,067,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 85 | 119 | 175 | 425 | 595 | 1,031 | 2,975 | 5,155 | 7,217 | 17,527 | 25,775 | 36,085 | 87,635 | 122,689 | 180,425 | 438,175 | 613,445 | 3,067,225 |
| -1 | -5 | -7 | -17 | -25 | -35 | -85 | -119 | -175 | -425 | -595 | -1,031 | -2,975 | -5,155 | -7,217 | -17,527 | -25,775 | -36,085 | -87,635 | -122,689 | -180,425 | -438,175 | -613,445 | -3,067,225 |
