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 55,313,351, 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 | 55,313,351 | |
| -1 | -55,313,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,313,351.
Example:
1 x 55,313,351 = 55,313,351
and
-1 x -55,313,351 = 55,313,351
Notice both answers equal 55,313,351
With that explanation out of the way, let's continue. Next, we take the number 55,313,351 and divide it by 2:
55,313,351 ÷ 2 = 27,656,675.5
If the quotient is a whole number, then 2 and 27,656,675.5 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 | 55,313,351 | |
| -1 | -55,313,351 |
Now, we try dividing 55,313,351 by 3:
55,313,351 ÷ 3 = 18,437,783.6667
If the quotient is a whole number, then 3 and 18,437,783.6667 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 | 55,313,351 | |
| -1 | -55,313,351 |
Let's try dividing by 4:
55,313,351 ÷ 4 = 13,828,337.75
If the quotient is a whole number, then 4 and 13,828,337.75 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 | 55,313,351 | |
| -1 | 55,313,351 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 79 | 817 | 857 | 1,501 | 3,397 | 16,283 | 36,851 | 64,543 | 67,703 | 700,169 | 1,286,357 | 2,911,229 | 55,313,351 |
| -1 | -19 | -43 | -79 | -817 | -857 | -1,501 | -3,397 | -16,283 | -36,851 | -64,543 | -67,703 | -700,169 | -1,286,357 | -2,911,229 | -55,313,351 |
