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 51,351,053, 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 | 51,351,053 | |
| -1 | -51,351,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,351,053.
Example:
1 x 51,351,053 = 51,351,053
and
-1 x -51,351,053 = 51,351,053
Notice both answers equal 51,351,053
With that explanation out of the way, let's continue. Next, we take the number 51,351,053 and divide it by 2:
51,351,053 ÷ 2 = 25,675,526.5
If the quotient is a whole number, then 2 and 25,675,526.5 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 | 51,351,053 | |
| -1 | -51,351,053 |
Now, we try dividing 51,351,053 by 3:
51,351,053 ÷ 3 = 17,117,017.6667
If the quotient is a whole number, then 3 and 17,117,017.6667 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 | 51,351,053 | |
| -1 | -51,351,053 |
Let's try dividing by 4:
51,351,053 ÷ 4 = 12,837,763.25
If the quotient is a whole number, then 4 and 12,837,763.25 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 | 51,351,053 | |
| -1 | 51,351,053 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 127 | 247 | 1,637 | 1,651 | 2,413 | 21,281 | 31,103 | 31,369 | 207,899 | 404,339 | 2,702,687 | 3,950,081 | 51,351,053 |
| -1 | -13 | -19 | -127 | -247 | -1,637 | -1,651 | -2,413 | -21,281 | -31,103 | -31,369 | -207,899 | -404,339 | -2,702,687 | -3,950,081 | -51,351,053 |
