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 27,651,875, 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 | 27,651,875 | |
| -1 | -27,651,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,651,875.
Example:
1 x 27,651,875 = 27,651,875
and
-1 x -27,651,875 = 27,651,875
Notice both answers equal 27,651,875
With that explanation out of the way, let's continue. Next, we take the number 27,651,875 and divide it by 2:
27,651,875 ÷ 2 = 13,825,937.5
If the quotient is a whole number, then 2 and 13,825,937.5 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 | 27,651,875 | |
| -1 | -27,651,875 |
Now, we try dividing 27,651,875 by 3:
27,651,875 ÷ 3 = 9,217,291.6667
If the quotient is a whole number, then 3 and 9,217,291.6667 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 | 27,651,875 | |
| -1 | -27,651,875 |
Let's try dividing by 4:
27,651,875 ÷ 4 = 6,912,968.75
If the quotient is a whole number, then 4 and 6,912,968.75 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 | 27,651,875 | |
| -1 | 27,651,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 151 | 293 | 625 | 755 | 1,465 | 3,775 | 7,325 | 18,875 | 36,625 | 44,243 | 94,375 | 183,125 | 221,215 | 1,106,075 | 5,530,375 | 27,651,875 |
| -1 | -5 | -25 | -125 | -151 | -293 | -625 | -755 | -1,465 | -3,775 | -7,325 | -18,875 | -36,625 | -44,243 | -94,375 | -183,125 | -221,215 | -1,106,075 | -5,530,375 | -27,651,875 |
