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 51,553,313, 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 | 51,553,313 | |
| -1 | -51,553,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,553,313.
Example:
1 x 51,553,313 = 51,553,313
and
-1 x -51,553,313 = 51,553,313
Notice both answers equal 51,553,313
With that explanation out of the way, let's continue. Next, we take the number 51,553,313 and divide it by 2:
51,553,313 ÷ 2 = 25,776,656.5
If the quotient is a whole number, then 2 and 25,776,656.5 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 | 51,553,313 | |
| -1 | -51,553,313 |
Now, we try dividing 51,553,313 by 3:
51,553,313 ÷ 3 = 17,184,437.6667
If the quotient is a whole number, then 3 and 17,184,437.6667 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 | 51,553,313 | |
| -1 | -51,553,313 |
Let's try dividing by 4:
51,553,313 ÷ 4 = 12,888,328.25
If the quotient is a whole number, then 4 and 12,888,328.25 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 | 51,553,313 | |
| -1 | 51,553,313 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 71 | 329 | 497 | 2,207 | 3,337 | 15,449 | 23,359 | 103,729 | 156,697 | 726,103 | 1,096,879 | 7,364,759 | 51,553,313 |
| -1 | -7 | -47 | -71 | -329 | -497 | -2,207 | -3,337 | -15,449 | -23,359 | -103,729 | -156,697 | -726,103 | -1,096,879 | -7,364,759 | -51,553,313 |
