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 4,185,773, 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 | 4,185,773 | |
| -1 | -4,185,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,185,773.
Example:
1 x 4,185,773 = 4,185,773
and
-1 x -4,185,773 = 4,185,773
Notice both answers equal 4,185,773
With that explanation out of the way, let's continue. Next, we take the number 4,185,773 and divide it by 2:
4,185,773 ÷ 2 = 2,092,886.5
If the quotient is a whole number, then 2 and 2,092,886.5 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 | 4,185,773 | |
| -1 | -4,185,773 |
Now, we try dividing 4,185,773 by 3:
4,185,773 ÷ 3 = 1,395,257.6667
If the quotient is a whole number, then 3 and 1,395,257.6667 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 | 4,185,773 | |
| -1 | -4,185,773 |
Let's try dividing by 4:
4,185,773 ÷ 4 = 1,046,443.25
If the quotient is a whole number, then 4 and 1,046,443.25 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 | 4,185,773 | |
| -1 | 4,185,773 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 47 | 83 | 1,073 | 1,363 | 1,739 | 2,407 | 3,071 | 3,901 | 50,431 | 89,059 | 113,129 | 144,337 | 4,185,773 |
| -1 | -29 | -37 | -47 | -83 | -1,073 | -1,363 | -1,739 | -2,407 | -3,071 | -3,901 | -50,431 | -89,059 | -113,129 | -144,337 | -4,185,773 |
