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 49,085,729, 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 | 49,085,729 | |
| -1 | -49,085,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,085,729.
Example:
1 x 49,085,729 = 49,085,729
and
-1 x -49,085,729 = 49,085,729
Notice both answers equal 49,085,729
With that explanation out of the way, let's continue. Next, we take the number 49,085,729 and divide it by 2:
49,085,729 ÷ 2 = 24,542,864.5
If the quotient is a whole number, then 2 and 24,542,864.5 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 | 49,085,729 | |
| -1 | -49,085,729 |
Now, we try dividing 49,085,729 by 3:
49,085,729 ÷ 3 = 16,361,909.6667
If the quotient is a whole number, then 3 and 16,361,909.6667 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 | 49,085,729 | |
| -1 | -49,085,729 |
Let's try dividing by 4:
49,085,729 ÷ 4 = 12,271,432.25
If the quotient is a whole number, then 4 and 12,271,432.25 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 | 49,085,729 | |
| -1 | 49,085,729 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 443 | 1,439 | 3,101 | 4,873 | 10,073 | 15,829 | 34,111 | 110,803 | 637,477 | 4,462,339 | 7,012,247 | 49,085,729 |
| -1 | -7 | -11 | -77 | -443 | -1,439 | -3,101 | -4,873 | -10,073 | -15,829 | -34,111 | -110,803 | -637,477 | -4,462,339 | -7,012,247 | -49,085,729 |
