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 4,142,435, 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 | 4,142,435 | |
| -1 | -4,142,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,142,435.
Example:
1 x 4,142,435 = 4,142,435
and
-1 x -4,142,435 = 4,142,435
Notice both answers equal 4,142,435
With that explanation out of the way, let's continue. Next, we take the number 4,142,435 and divide it by 2:
4,142,435 ÷ 2 = 2,071,217.5
If the quotient is a whole number, then 2 and 2,071,217.5 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 | 4,142,435 | |
| -1 | -4,142,435 |
Now, we try dividing 4,142,435 by 3:
4,142,435 ÷ 3 = 1,380,811.6667
If the quotient is a whole number, then 3 and 1,380,811.6667 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 | 4,142,435 | |
| -1 | -4,142,435 |
Let's try dividing by 4:
4,142,435 ÷ 4 = 1,035,608.75
If the quotient is a whole number, then 4 and 1,035,608.75 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 | 4,142,435 | |
| -1 | 4,142,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 121 | 167 | 205 | 451 | 605 | 835 | 1,837 | 2,255 | 4,961 | 6,847 | 9,185 | 20,207 | 24,805 | 34,235 | 75,317 | 101,035 | 376,585 | 828,487 | 4,142,435 |
| -1 | -5 | -11 | -41 | -55 | -121 | -167 | -205 | -451 | -605 | -835 | -1,837 | -2,255 | -4,961 | -6,847 | -9,185 | -20,207 | -24,805 | -34,235 | -75,317 | -101,035 | -376,585 | -828,487 | -4,142,435 |
