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 55,310,453, 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 | 55,310,453 | |
| -1 | -55,310,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,310,453.
Example:
1 x 55,310,453 = 55,310,453
and
-1 x -55,310,453 = 55,310,453
Notice both answers equal 55,310,453
With that explanation out of the way, let's continue. Next, we take the number 55,310,453 and divide it by 2:
55,310,453 ÷ 2 = 27,655,226.5
If the quotient is a whole number, then 2 and 27,655,226.5 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 | 55,310,453 | |
| -1 | -55,310,453 |
Now, we try dividing 55,310,453 by 3:
55,310,453 ÷ 3 = 18,436,817.6667
If the quotient is a whole number, then 3 and 18,436,817.6667 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 | 55,310,453 | |
| -1 | -55,310,453 |
Let's try dividing by 4:
55,310,453 ÷ 4 = 13,827,613.25
If the quotient is a whole number, then 4 and 13,827,613.25 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 | 55,310,453 | |
| -1 | 55,310,453 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 83 | 319 | 913 | 2,089 | 2,407 | 22,979 | 26,477 | 60,581 | 173,387 | 666,391 | 1,907,257 | 5,028,223 | 55,310,453 |
| -1 | -11 | -29 | -83 | -319 | -913 | -2,089 | -2,407 | -22,979 | -26,477 | -60,581 | -173,387 | -666,391 | -1,907,257 | -5,028,223 | -55,310,453 |
