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 1,614,305, 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 | 1,614,305 | |
| -1 | -1,614,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,614,305.
Example:
1 x 1,614,305 = 1,614,305
and
-1 x -1,614,305 = 1,614,305
Notice both answers equal 1,614,305
With that explanation out of the way, let's continue. Next, we take the number 1,614,305 and divide it by 2:
1,614,305 ÷ 2 = 807,152.5
If the quotient is a whole number, then 2 and 807,152.5 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 | 1,614,305 | |
| -1 | -1,614,305 |
Now, we try dividing 1,614,305 by 3:
1,614,305 ÷ 3 = 538,101.6667
If the quotient is a whole number, then 3 and 538,101.6667 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 | 1,614,305 | |
| -1 | -1,614,305 |
Let's try dividing by 4:
1,614,305 ÷ 4 = 403,576.25
If the quotient is a whole number, then 4 and 403,576.25 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 | 1,614,305 | |
| -1 | 1,614,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 385 | 539 | 599 | 2,695 | 2,995 | 4,193 | 6,589 | 20,965 | 29,351 | 32,945 | 46,123 | 146,755 | 230,615 | 322,861 | 1,614,305 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -385 | -539 | -599 | -2,695 | -2,995 | -4,193 | -6,589 | -20,965 | -29,351 | -32,945 | -46,123 | -146,755 | -230,615 | -322,861 | -1,614,305 |
