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 27,477,935, 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 | 27,477,935 | |
| -1 | -27,477,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,477,935.
Example:
1 x 27,477,935 = 27,477,935
and
-1 x -27,477,935 = 27,477,935
Notice both answers equal 27,477,935
With that explanation out of the way, let's continue. Next, we take the number 27,477,935 and divide it by 2:
27,477,935 ÷ 2 = 13,738,967.5
If the quotient is a whole number, then 2 and 13,738,967.5 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 | 27,477,935 | |
| -1 | -27,477,935 |
Now, we try dividing 27,477,935 by 3:
27,477,935 ÷ 3 = 9,159,311.6667
If the quotient is a whole number, then 3 and 9,159,311.6667 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 | 27,477,935 | |
| -1 | -27,477,935 |
Let's try dividing by 4:
27,477,935 ÷ 4 = 6,869,483.75
If the quotient is a whole number, then 4 and 6,869,483.75 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 | 27,477,935 | |
| -1 | 27,477,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 145 | 155 | 899 | 4,495 | 6,113 | 30,565 | 177,277 | 189,503 | 886,385 | 947,515 | 5,495,587 | 27,477,935 |
| -1 | -5 | -29 | -31 | -145 | -155 | -899 | -4,495 | -6,113 | -30,565 | -177,277 | -189,503 | -886,385 | -947,515 | -5,495,587 | -27,477,935 |
