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 3,105,737, 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 | 3,105,737 | |
-1 | -3,105,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,105,737.
Example:
1 x 3,105,737 = 3,105,737
and
-1 x -3,105,737 = 3,105,737
Notice both answers equal 3,105,737
With that explanation out of the way, let's continue. Next, we take the number 3,105,737 and divide it by 2:
3,105,737 ÷ 2 = 1,552,868.5
If the quotient is a whole number, then 2 and 1,552,868.5 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 | 3,105,737 | |
-1 | -3,105,737 |
Now, we try dividing 3,105,737 by 3:
3,105,737 ÷ 3 = 1,035,245.6667
If the quotient is a whole number, then 3 and 1,035,245.6667 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 | 3,105,737 | |
-1 | -3,105,737 |
Let's try dividing by 4:
3,105,737 ÷ 4 = 776,434.25
If the quotient is a whole number, then 4 and 776,434.25 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 | 3,105,737 | |
-1 | 3,105,737 |
If you did it right, you will end up with this table:
1 | 109 | 28,493 | 3,105,737 |
-1 | -109 | -28,493 | -3,105,737 |
