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 55,314,245, 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 | 55,314,245 | |
| -1 | -55,314,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,314,245.
Example:
1 x 55,314,245 = 55,314,245
and
-1 x -55,314,245 = 55,314,245
Notice both answers equal 55,314,245
With that explanation out of the way, let's continue. Next, we take the number 55,314,245 and divide it by 2:
55,314,245 ÷ 2 = 27,657,122.5
If the quotient is a whole number, then 2 and 27,657,122.5 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 | 55,314,245 | |
| -1 | -55,314,245 |
Now, we try dividing 55,314,245 by 3:
55,314,245 ÷ 3 = 18,438,081.6667
If the quotient is a whole number, then 3 and 18,438,081.6667 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 | 55,314,245 | |
| -1 | -55,314,245 |
Let's try dividing by 4:
55,314,245 ÷ 4 = 13,828,561.25
If the quotient is a whole number, then 4 and 13,828,561.25 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 | 55,314,245 | |
| -1 | 55,314,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 29,819 | 149,095 | 208,733 | 1,043,665 | 1,580,407 | 7,902,035 | 11,062,849 | 55,314,245 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -29,819 | -149,095 | -208,733 | -1,043,665 | -1,580,407 | -7,902,035 | -11,062,849 | -55,314,245 |
