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 28,527,835, 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 | 28,527,835 | |
| -1 | -28,527,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,527,835.
Example:
1 x 28,527,835 = 28,527,835
and
-1 x -28,527,835 = 28,527,835
Notice both answers equal 28,527,835
With that explanation out of the way, let's continue. Next, we take the number 28,527,835 and divide it by 2:
28,527,835 ÷ 2 = 14,263,917.5
If the quotient is a whole number, then 2 and 14,263,917.5 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 | 28,527,835 | |
| -1 | -28,527,835 |
Now, we try dividing 28,527,835 by 3:
28,527,835 ÷ 3 = 9,509,278.3333
If the quotient is a whole number, then 3 and 9,509,278.3333 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 | 28,527,835 | |
| -1 | -28,527,835 |
Let's try dividing by 4:
28,527,835 ÷ 4 = 7,131,958.75
If the quotient is a whole number, then 4 and 7,131,958.75 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 | 28,527,835 | |
| -1 | 28,527,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 42,899 | 214,495 | 300,293 | 815,081 | 1,501,465 | 4,075,405 | 5,705,567 | 28,527,835 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -42,899 | -214,495 | -300,293 | -815,081 | -1,501,465 | -4,075,405 | -5,705,567 | -28,527,835 |
