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 4,905,173, 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 | 4,905,173 | |
| -1 | -4,905,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,905,173.
Example:
1 x 4,905,173 = 4,905,173
and
-1 x -4,905,173 = 4,905,173
Notice both answers equal 4,905,173
With that explanation out of the way, let's continue. Next, we take the number 4,905,173 and divide it by 2:
4,905,173 ÷ 2 = 2,452,586.5
If the quotient is a whole number, then 2 and 2,452,586.5 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 | 4,905,173 | |
| -1 | -4,905,173 |
Now, we try dividing 4,905,173 by 3:
4,905,173 ÷ 3 = 1,635,057.6667
If the quotient is a whole number, then 3 and 1,635,057.6667 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 | 4,905,173 | |
| -1 | -4,905,173 |
Let's try dividing by 4:
4,905,173 ÷ 4 = 1,226,293.25
If the quotient is a whole number, then 4 and 1,226,293.25 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 | 4,905,173 | |
| -1 | 4,905,173 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 2,837 | 19,859 | 36,881 | 53,903 | 258,167 | 377,321 | 700,739 | 4,905,173 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -2,837 | -19,859 | -36,881 | -53,903 | -258,167 | -377,321 | -700,739 | -4,905,173 |
