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 4,157,605, 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 | 4,157,605 | |
| -1 | -4,157,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,157,605.
Example:
1 x 4,157,605 = 4,157,605
and
-1 x -4,157,605 = 4,157,605
Notice both answers equal 4,157,605
With that explanation out of the way, let's continue. Next, we take the number 4,157,605 and divide it by 2:
4,157,605 ÷ 2 = 2,078,802.5
If the quotient is a whole number, then 2 and 2,078,802.5 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 | 4,157,605 | |
| -1 | -4,157,605 |
Now, we try dividing 4,157,605 by 3:
4,157,605 ÷ 3 = 1,385,868.3333
If the quotient is a whole number, then 3 and 1,385,868.3333 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 | 4,157,605 | |
| -1 | -4,157,605 |
Let's try dividing by 4:
4,157,605 ÷ 4 = 1,039,401.25
If the quotient is a whole number, then 4 and 1,039,401.25 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 | 4,157,605 | |
| -1 | 4,157,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 41 | 85 | 205 | 697 | 1,193 | 3,485 | 5,965 | 20,281 | 48,913 | 101,405 | 244,565 | 831,521 | 4,157,605 |
| -1 | -5 | -17 | -41 | -85 | -205 | -697 | -1,193 | -3,485 | -5,965 | -20,281 | -48,913 | -101,405 | -244,565 | -831,521 | -4,157,605 |
