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 3,485,615, 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 | 3,485,615 | |
| -1 | -3,485,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,485,615.
Example:
1 x 3,485,615 = 3,485,615
and
-1 x -3,485,615 = 3,485,615
Notice both answers equal 3,485,615
With that explanation out of the way, let's continue. Next, we take the number 3,485,615 and divide it by 2:
3,485,615 ÷ 2 = 1,742,807.5
If the quotient is a whole number, then 2 and 1,742,807.5 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 | 3,485,615 | |
| -1 | -3,485,615 |
Now, we try dividing 3,485,615 by 3:
3,485,615 ÷ 3 = 1,161,871.6667
If the quotient is a whole number, then 3 and 1,161,871.6667 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 | 3,485,615 | |
| -1 | -3,485,615 |
Let's try dividing by 4:
3,485,615 ÷ 4 = 871,403.75
If the quotient is a whole number, then 4 and 871,403.75 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 | 3,485,615 | |
| -1 | 3,485,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 49 | 205 | 245 | 287 | 347 | 1,435 | 1,735 | 2,009 | 2,429 | 10,045 | 12,145 | 14,227 | 17,003 | 71,135 | 85,015 | 99,589 | 497,945 | 697,123 | 3,485,615 |
| -1 | -5 | -7 | -35 | -41 | -49 | -205 | -245 | -287 | -347 | -1,435 | -1,735 | -2,009 | -2,429 | -10,045 | -12,145 | -14,227 | -17,003 | -71,135 | -85,015 | -99,589 | -497,945 | -697,123 | -3,485,615 |
