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 40,554,227, 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 | 40,554,227 | |
| -1 | -40,554,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,554,227.
Example:
1 x 40,554,227 = 40,554,227
and
-1 x -40,554,227 = 40,554,227
Notice both answers equal 40,554,227
With that explanation out of the way, let's continue. Next, we take the number 40,554,227 and divide it by 2:
40,554,227 ÷ 2 = 20,277,113.5
If the quotient is a whole number, then 2 and 20,277,113.5 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 | 40,554,227 | |
| -1 | -40,554,227 |
Now, we try dividing 40,554,227 by 3:
40,554,227 ÷ 3 = 13,518,075.6667
If the quotient is a whole number, then 3 and 13,518,075.6667 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 | 40,554,227 | |
| -1 | -40,554,227 |
Let's try dividing by 4:
40,554,227 ÷ 4 = 10,138,556.75
If the quotient is a whole number, then 4 and 10,138,556.75 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 | 40,554,227 | |
| -1 | 40,554,227 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 101 | 133 | 707 | 1,919 | 3,019 | 13,433 | 21,133 | 57,361 | 304,919 | 401,527 | 2,134,433 | 5,793,461 | 40,554,227 |
| -1 | -7 | -19 | -101 | -133 | -707 | -1,919 | -3,019 | -13,433 | -21,133 | -57,361 | -304,919 | -401,527 | -2,134,433 | -5,793,461 | -40,554,227 |
