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 4,224,605, 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 | 4,224,605 | |
| -1 | -4,224,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,224,605.
Example:
1 x 4,224,605 = 4,224,605
and
-1 x -4,224,605 = 4,224,605
Notice both answers equal 4,224,605
With that explanation out of the way, let's continue. Next, we take the number 4,224,605 and divide it by 2:
4,224,605 ÷ 2 = 2,112,302.5
If the quotient is a whole number, then 2 and 2,112,302.5 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 | 4,224,605 | |
| -1 | -4,224,605 |
Now, we try dividing 4,224,605 by 3:
4,224,605 ÷ 3 = 1,408,201.6667
If the quotient is a whole number, then 3 and 1,408,201.6667 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 | 4,224,605 | |
| -1 | -4,224,605 |
Let's try dividing by 4:
4,224,605 ÷ 4 = 1,056,151.25
If the quotient is a whole number, then 4 and 1,056,151.25 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 | 4,224,605 | |
| -1 | 4,224,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 10,973 | 54,865 | 76,811 | 120,703 | 384,055 | 603,515 | 844,921 | 4,224,605 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -10,973 | -54,865 | -76,811 | -120,703 | -384,055 | -603,515 | -844,921 | -4,224,605 |
