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 55,562,227, 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 | 55,562,227 | |
| -1 | -55,562,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,562,227.
Example:
1 x 55,562,227 = 55,562,227
and
-1 x -55,562,227 = 55,562,227
Notice both answers equal 55,562,227
With that explanation out of the way, let's continue. Next, we take the number 55,562,227 and divide it by 2:
55,562,227 ÷ 2 = 27,781,113.5
If the quotient is a whole number, then 2 and 27,781,113.5 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 | 55,562,227 | |
| -1 | -55,562,227 |
Now, we try dividing 55,562,227 by 3:
55,562,227 ÷ 3 = 18,520,742.3333
If the quotient is a whole number, then 3 and 18,520,742.3333 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 | 55,562,227 | |
| -1 | -55,562,227 |
Let's try dividing by 4:
55,562,227 ÷ 4 = 13,890,556.75
If the quotient is a whole number, then 4 and 13,890,556.75 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 | 55,562,227 | |
| -1 | 55,562,227 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 161 | 343 | 1,127 | 7,043 | 7,889 | 49,301 | 161,989 | 345,107 | 1,133,923 | 2,415,749 | 7,937,461 | 55,562,227 |
| -1 | -7 | -23 | -49 | -161 | -343 | -1,127 | -7,043 | -7,889 | -49,301 | -161,989 | -345,107 | -1,133,923 | -2,415,749 | -7,937,461 | -55,562,227 |
