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 51,316,055, 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 | 51,316,055 | |
| -1 | -51,316,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,316,055.
Example:
1 x 51,316,055 = 51,316,055
and
-1 x -51,316,055 = 51,316,055
Notice both answers equal 51,316,055
With that explanation out of the way, let's continue. Next, we take the number 51,316,055 and divide it by 2:
51,316,055 ÷ 2 = 25,658,027.5
If the quotient is a whole number, then 2 and 25,658,027.5 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 | 51,316,055 | |
| -1 | -51,316,055 |
Now, we try dividing 51,316,055 by 3:
51,316,055 ÷ 3 = 17,105,351.6667
If the quotient is a whole number, then 3 and 17,105,351.6667 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 | 51,316,055 | |
| -1 | -51,316,055 |
Let's try dividing by 4:
51,316,055 ÷ 4 = 12,829,013.75
If the quotient is a whole number, then 4 and 12,829,013.75 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 | 51,316,055 | |
| -1 | 51,316,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 77,167 | 385,835 | 540,169 | 1,466,173 | 2,700,845 | 7,330,865 | 10,263,211 | 51,316,055 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -77,167 | -385,835 | -540,169 | -1,466,173 | -2,700,845 | -7,330,865 | -10,263,211 | -51,316,055 |
