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 55,162,165, 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 | 55,162,165 | |
| -1 | -55,162,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,162,165.
Example:
1 x 55,162,165 = 55,162,165
and
-1 x -55,162,165 = 55,162,165
Notice both answers equal 55,162,165
With that explanation out of the way, let's continue. Next, we take the number 55,162,165 and divide it by 2:
55,162,165 ÷ 2 = 27,581,082.5
If the quotient is a whole number, then 2 and 27,581,082.5 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 | 55,162,165 | |
| -1 | -55,162,165 |
Now, we try dividing 55,162,165 by 3:
55,162,165 ÷ 3 = 18,387,388.3333
If the quotient is a whole number, then 3 and 18,387,388.3333 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 | 55,162,165 | |
| -1 | -55,162,165 |
Let's try dividing by 4:
55,162,165 ÷ 4 = 13,790,541.25
If the quotient is a whole number, then 4 and 13,790,541.25 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 | 55,162,165 | |
| -1 | 55,162,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 103 | 115 | 515 | 2,369 | 4,657 | 11,845 | 23,285 | 107,111 | 479,671 | 535,555 | 2,398,355 | 11,032,433 | 55,162,165 |
| -1 | -5 | -23 | -103 | -115 | -515 | -2,369 | -4,657 | -11,845 | -23,285 | -107,111 | -479,671 | -535,555 | -2,398,355 | -11,032,433 | -55,162,165 |
