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 55,283,507, 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 | 55,283,507 | |
| -1 | -55,283,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,283,507.
Example:
1 x 55,283,507 = 55,283,507
and
-1 x -55,283,507 = 55,283,507
Notice both answers equal 55,283,507
With that explanation out of the way, let's continue. Next, we take the number 55,283,507 and divide it by 2:
55,283,507 ÷ 2 = 27,641,753.5
If the quotient is a whole number, then 2 and 27,641,753.5 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 | 55,283,507 | |
| -1 | -55,283,507 |
Now, we try dividing 55,283,507 by 3:
55,283,507 ÷ 3 = 18,427,835.6667
If the quotient is a whole number, then 3 and 18,427,835.6667 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 | 55,283,507 | |
| -1 | -55,283,507 |
Let's try dividing by 4:
55,283,507 ÷ 4 = 13,820,876.75
If the quotient is a whole number, then 4 and 13,820,876.75 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 | 55,283,507 | |
| -1 | 55,283,507 |
If you did it right, you will end up with this table:
| 1 | 17 | 61 | 89 | 599 | 1,037 | 1,513 | 5,429 | 10,183 | 36,539 | 53,311 | 92,293 | 621,163 | 906,287 | 3,251,971 | 55,283,507 |
| -1 | -17 | -61 | -89 | -599 | -1,037 | -1,513 | -5,429 | -10,183 | -36,539 | -53,311 | -92,293 | -621,163 | -906,287 | -3,251,971 | -55,283,507 |
