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 28,943,035, 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 | 28,943,035 | |
| -1 | -28,943,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,943,035.
Example:
1 x 28,943,035 = 28,943,035
and
-1 x -28,943,035 = 28,943,035
Notice both answers equal 28,943,035
With that explanation out of the way, let's continue. Next, we take the number 28,943,035 and divide it by 2:
28,943,035 ÷ 2 = 14,471,517.5
If the quotient is a whole number, then 2 and 14,471,517.5 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 | 28,943,035 | |
| -1 | -28,943,035 |
Now, we try dividing 28,943,035 by 3:
28,943,035 ÷ 3 = 9,647,678.3333
If the quotient is a whole number, then 3 and 9,647,678.3333 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 | 28,943,035 | |
| -1 | -28,943,035 |
Let's try dividing by 4:
28,943,035 ÷ 4 = 7,235,758.75
If the quotient is a whole number, then 4 and 7,235,758.75 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 | 28,943,035 | |
| -1 | 28,943,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 9,929 | 49,645 | 109,219 | 526,237 | 546,095 | 2,631,185 | 5,788,607 | 28,943,035 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -9,929 | -49,645 | -109,219 | -526,237 | -546,095 | -2,631,185 | -5,788,607 | -28,943,035 |
