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 3,799,873, 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 | 3,799,873 | |
| -1 | -3,799,873 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,799,873.
Example:
1 x 3,799,873 = 3,799,873
and
-1 x -3,799,873 = 3,799,873
Notice both answers equal 3,799,873
With that explanation out of the way, let's continue. Next, we take the number 3,799,873 and divide it by 2:
3,799,873 ÷ 2 = 1,899,936.5
If the quotient is a whole number, then 2 and 1,899,936.5 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 | 3,799,873 | |
| -1 | -3,799,873 |
Now, we try dividing 3,799,873 by 3:
3,799,873 ÷ 3 = 1,266,624.3333
If the quotient is a whole number, then 3 and 1,266,624.3333 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 | 3,799,873 | |
| -1 | -3,799,873 |
Let's try dividing by 4:
3,799,873 ÷ 4 = 949,968.25
If the quotient is a whole number, then 4 and 949,968.25 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 | 3,799,873 | |
| -1 | 3,799,873 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 61 | 77 | 427 | 671 | 809 | 4,697 | 5,663 | 8,899 | 49,349 | 62,293 | 345,443 | 542,839 | 3,799,873 |
| -1 | -7 | -11 | -61 | -77 | -427 | -671 | -809 | -4,697 | -5,663 | -8,899 | -49,349 | -62,293 | -345,443 | -542,839 | -3,799,873 |
