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 51,111,655, 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 | 51,111,655 | |
| -1 | -51,111,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,111,655.
Example:
1 x 51,111,655 = 51,111,655
and
-1 x -51,111,655 = 51,111,655
Notice both answers equal 51,111,655
With that explanation out of the way, let's continue. Next, we take the number 51,111,655 and divide it by 2:
51,111,655 ÷ 2 = 25,555,827.5
If the quotient is a whole number, then 2 and 25,555,827.5 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 | 51,111,655 | |
| -1 | -51,111,655 |
Now, we try dividing 51,111,655 by 3:
51,111,655 ÷ 3 = 17,037,218.3333
If the quotient is a whole number, then 3 and 17,037,218.3333 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 | 51,111,655 | |
| -1 | -51,111,655 |
Let's try dividing by 4:
51,111,655 ÷ 4 = 12,777,913.75
If the quotient is a whole number, then 4 and 12,777,913.75 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 | 51,111,655 | |
| -1 | 51,111,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 229 | 245 | 911 | 1,145 | 1,603 | 4,555 | 6,377 | 8,015 | 11,221 | 31,885 | 44,639 | 56,105 | 208,619 | 223,195 | 1,043,095 | 1,460,333 | 7,301,665 | 10,222,331 | 51,111,655 |
| -1 | -5 | -7 | -35 | -49 | -229 | -245 | -911 | -1,145 | -1,603 | -4,555 | -6,377 | -8,015 | -11,221 | -31,885 | -44,639 | -56,105 | -208,619 | -223,195 | -1,043,095 | -1,460,333 | -7,301,665 | -10,222,331 | -51,111,655 |
