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 45,477,811, 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 | 45,477,811 | |
| -1 | -45,477,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,477,811.
Example:
1 x 45,477,811 = 45,477,811
and
-1 x -45,477,811 = 45,477,811
Notice both answers equal 45,477,811
With that explanation out of the way, let's continue. Next, we take the number 45,477,811 and divide it by 2:
45,477,811 ÷ 2 = 22,738,905.5
If the quotient is a whole number, then 2 and 22,738,905.5 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 | 45,477,811 | |
| -1 | -45,477,811 |
Now, we try dividing 45,477,811 by 3:
45,477,811 ÷ 3 = 15,159,270.3333
If the quotient is a whole number, then 3 and 15,159,270.3333 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 | 45,477,811 | |
| -1 | -45,477,811 |
Let's try dividing by 4:
45,477,811 ÷ 4 = 11,369,452.75
If the quotient is a whole number, then 4 and 11,369,452.75 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 | 45,477,811 | |
| -1 | 45,477,811 |
If you did it right, you will end up with this table:
| 1 | 19 | 47 | 127 | 401 | 893 | 2,413 | 5,969 | 7,619 | 18,847 | 50,927 | 113,411 | 358,093 | 967,613 | 2,393,569 | 45,477,811 |
| -1 | -19 | -47 | -127 | -401 | -893 | -2,413 | -5,969 | -7,619 | -18,847 | -50,927 | -113,411 | -358,093 | -967,613 | -2,393,569 | -45,477,811 |
