A:
Positive:
1 x 6115011111 x 5559101769 x 795197229 x 8459
Negative:
-1 x -61150111-11 x -5559101-769 x -79519-7229 x -8459
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 61,150,111, 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 | 61,150,111 | |
| -1 | -61,150,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,150,111.
Example:
1 x 61,150,111 = 61,150,111
and
-1 x -61,150,111 = 61,150,111
Notice both answers equal 61,150,111
With that explanation out of the way, let's continue. Next, we take the number 61,150,111 and divide it by 2:
61,150,111 ÷ 2 = 30,575,055.5
If the quotient is a whole number, then 2 and 30,575,055.5 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 | 61,150,111 | |
| -1 | -61,150,111 |
Now, we try dividing 61,150,111 by 3:
61,150,111 ÷ 3 = 20,383,370.3333
If the quotient is a whole number, then 3 and 20,383,370.3333 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 | 61,150,111 | |
| -1 | -61,150,111 |
Let's try dividing by 4:
61,150,111 ÷ 4 = 15,287,527.75
If the quotient is a whole number, then 4 and 15,287,527.75 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 | 61,150,111 | |
| -1 | 61,150,111 |
If you did it right, you will end up with this table:
| 1 | 11 | 769 | 7,229 | 8,459 | 79,519 | 5,559,101 | 61,150,111 |
| -1 | -11 | -769 | -7,229 | -8,459 | -79,519 | -5,559,101 | -61,150,111 |
