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 3,018,175, 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 | 3,018,175 | |
| -1 | -3,018,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,018,175.
Example:
1 x 3,018,175 = 3,018,175
and
-1 x -3,018,175 = 3,018,175
Notice both answers equal 3,018,175
With that explanation out of the way, let's continue. Next, we take the number 3,018,175 and divide it by 2:
3,018,175 ÷ 2 = 1,509,087.5
If the quotient is a whole number, then 2 and 1,509,087.5 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 | 3,018,175 | |
| -1 | -3,018,175 |
Now, we try dividing 3,018,175 by 3:
3,018,175 ÷ 3 = 1,006,058.3333
If the quotient is a whole number, then 3 and 1,006,058.3333 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 | 3,018,175 | |
| -1 | -3,018,175 |
Let's try dividing by 4:
3,018,175 ÷ 4 = 754,543.75
If the quotient is a whole number, then 4 and 754,543.75 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 | 3,018,175 | |
| -1 | 3,018,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 29 | 115 | 145 | 181 | 575 | 667 | 725 | 905 | 3,335 | 4,163 | 4,525 | 5,249 | 16,675 | 20,815 | 26,245 | 104,075 | 120,727 | 131,225 | 603,635 | 3,018,175 |
| -1 | -5 | -23 | -25 | -29 | -115 | -145 | -181 | -575 | -667 | -725 | -905 | -3,335 | -4,163 | -4,525 | -5,249 | -16,675 | -20,815 | -26,245 | -104,075 | -120,727 | -131,225 | -603,635 | -3,018,175 |
