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 4,928,105, 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 | 4,928,105 | |
| -1 | -4,928,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,928,105.
Example:
1 x 4,928,105 = 4,928,105
and
-1 x -4,928,105 = 4,928,105
Notice both answers equal 4,928,105
With that explanation out of the way, let's continue. Next, we take the number 4,928,105 and divide it by 2:
4,928,105 ÷ 2 = 2,464,052.5
If the quotient is a whole number, then 2 and 2,464,052.5 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 | 4,928,105 | |
| -1 | -4,928,105 |
Now, we try dividing 4,928,105 by 3:
4,928,105 ÷ 3 = 1,642,701.6667
If the quotient is a whole number, then 3 and 1,642,701.6667 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 | 4,928,105 | |
| -1 | -4,928,105 |
Let's try dividing by 4:
4,928,105 ÷ 4 = 1,232,026.25
If the quotient is a whole number, then 4 and 1,232,026.25 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 | 4,928,105 | |
| -1 | 4,928,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 10,831 | 54,155 | 75,817 | 140,803 | 379,085 | 704,015 | 985,621 | 4,928,105 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -10,831 | -54,155 | -75,817 | -140,803 | -379,085 | -704,015 | -985,621 | -4,928,105 |
