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 4,240,159, 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 | 4,240,159 | |
| -1 | -4,240,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,240,159.
Example:
1 x 4,240,159 = 4,240,159
and
-1 x -4,240,159 = 4,240,159
Notice both answers equal 4,240,159
With that explanation out of the way, let's continue. Next, we take the number 4,240,159 and divide it by 2:
4,240,159 ÷ 2 = 2,120,079.5
If the quotient is a whole number, then 2 and 2,120,079.5 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 | 4,240,159 | |
| -1 | -4,240,159 |
Now, we try dividing 4,240,159 by 3:
4,240,159 ÷ 3 = 1,413,386.3333
If the quotient is a whole number, then 3 and 1,413,386.3333 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 | 4,240,159 | |
| -1 | -4,240,159 |
Let's try dividing by 4:
4,240,159 ÷ 4 = 1,060,039.75
If the quotient is a whole number, then 4 and 1,060,039.75 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 | 4,240,159 | |
| -1 | 4,240,159 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 53 | 77 | 371 | 583 | 1,039 | 4,081 | 7,273 | 11,429 | 55,067 | 80,003 | 385,469 | 605,737 | 4,240,159 |
| -1 | -7 | -11 | -53 | -77 | -371 | -583 | -1,039 | -4,081 | -7,273 | -11,429 | -55,067 | -80,003 | -385,469 | -605,737 | -4,240,159 |
