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 51,613,955, 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 | 51,613,955 | |
| -1 | -51,613,955 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,613,955.
Example:
1 x 51,613,955 = 51,613,955
and
-1 x -51,613,955 = 51,613,955
Notice both answers equal 51,613,955
With that explanation out of the way, let's continue. Next, we take the number 51,613,955 and divide it by 2:
51,613,955 ÷ 2 = 25,806,977.5
If the quotient is a whole number, then 2 and 25,806,977.5 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 | 51,613,955 | |
| -1 | -51,613,955 |
Now, we try dividing 51,613,955 by 3:
51,613,955 ÷ 3 = 17,204,651.6667
If the quotient is a whole number, then 3 and 17,204,651.6667 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 | 51,613,955 | |
| -1 | -51,613,955 |
Let's try dividing by 4:
51,613,955 ÷ 4 = 12,903,488.75
If the quotient is a whole number, then 4 and 12,903,488.75 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 | 51,613,955 | |
| -1 | 51,613,955 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 289 | 391 | 1,445 | 1,553 | 1,955 | 6,647 | 7,765 | 26,401 | 33,235 | 35,719 | 132,005 | 178,595 | 448,817 | 607,223 | 2,244,085 | 3,036,115 | 10,322,791 | 51,613,955 |
| -1 | -5 | -17 | -23 | -85 | -115 | -289 | -391 | -1,445 | -1,553 | -1,955 | -6,647 | -7,765 | -26,401 | -33,235 | -35,719 | -132,005 | -178,595 | -448,817 | -607,223 | -2,244,085 | -3,036,115 | -10,322,791 | -51,613,955 |
