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 3,171,035, 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 | 3,171,035 | |
| -1 | -3,171,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,171,035.
Example:
1 x 3,171,035 = 3,171,035
and
-1 x -3,171,035 = 3,171,035
Notice both answers equal 3,171,035
With that explanation out of the way, let's continue. Next, we take the number 3,171,035 and divide it by 2:
3,171,035 ÷ 2 = 1,585,517.5
If the quotient is a whole number, then 2 and 1,585,517.5 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 | 3,171,035 | |
| -1 | -3,171,035 |
Now, we try dividing 3,171,035 by 3:
3,171,035 ÷ 3 = 1,057,011.6667
If the quotient is a whole number, then 3 and 1,057,011.6667 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 | 3,171,035 | |
| -1 | -3,171,035 |
Let's try dividing by 4:
3,171,035 ÷ 4 = 792,758.75
If the quotient is a whole number, then 4 and 792,758.75 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 | 3,171,035 | |
| -1 | 3,171,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 49 | 215 | 245 | 301 | 343 | 1,505 | 1,715 | 1,849 | 2,107 | 9,245 | 10,535 | 12,943 | 14,749 | 64,715 | 73,745 | 90,601 | 453,005 | 634,207 | 3,171,035 |
| -1 | -5 | -7 | -35 | -43 | -49 | -215 | -245 | -301 | -343 | -1,505 | -1,715 | -1,849 | -2,107 | -9,245 | -10,535 | -12,943 | -14,749 | -64,715 | -73,745 | -90,601 | -453,005 | -634,207 | -3,171,035 |
