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 4,285,015, 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 | 4,285,015 | |
| -1 | -4,285,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,285,015.
Example:
1 x 4,285,015 = 4,285,015
and
-1 x -4,285,015 = 4,285,015
Notice both answers equal 4,285,015
With that explanation out of the way, let's continue. Next, we take the number 4,285,015 and divide it by 2:
4,285,015 ÷ 2 = 2,142,507.5
If the quotient is a whole number, then 2 and 2,142,507.5 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 | 4,285,015 | |
| -1 | -4,285,015 |
Now, we try dividing 4,285,015 by 3:
4,285,015 ÷ 3 = 1,428,338.3333
If the quotient is a whole number, then 3 and 1,428,338.3333 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 | 4,285,015 | |
| -1 | -4,285,015 |
Let's try dividing by 4:
4,285,015 ÷ 4 = 1,071,253.75
If the quotient is a whole number, then 4 and 1,071,253.75 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 | 4,285,015 | |
| -1 | 4,285,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 5,323 | 26,615 | 37,261 | 122,429 | 186,305 | 612,145 | 857,003 | 4,285,015 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -5,323 | -26,615 | -37,261 | -122,429 | -186,305 | -612,145 | -857,003 | -4,285,015 |
