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 55,435,285, 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 | 55,435,285 | |
| -1 | -55,435,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,435,285.
Example:
1 x 55,435,285 = 55,435,285
and
-1 x -55,435,285 = 55,435,285
Notice both answers equal 55,435,285
With that explanation out of the way, let's continue. Next, we take the number 55,435,285 and divide it by 2:
55,435,285 ÷ 2 = 27,717,642.5
If the quotient is a whole number, then 2 and 27,717,642.5 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 | 55,435,285 | |
| -1 | -55,435,285 |
Now, we try dividing 55,435,285 by 3:
55,435,285 ÷ 3 = 18,478,428.3333
If the quotient is a whole number, then 3 and 18,478,428.3333 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 | 55,435,285 | |
| -1 | -55,435,285 |
Let's try dividing by 4:
55,435,285 ÷ 4 = 13,858,821.25
If the quotient is a whole number, then 4 and 13,858,821.25 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 | 55,435,285 | |
| -1 | 55,435,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 83 | 139 | 155 | 415 | 695 | 961 | 2,573 | 4,309 | 4,805 | 11,537 | 12,865 | 21,545 | 57,685 | 79,763 | 133,579 | 357,647 | 398,815 | 667,895 | 1,788,235 | 11,087,057 | 55,435,285 |
| -1 | -5 | -31 | -83 | -139 | -155 | -415 | -695 | -961 | -2,573 | -4,309 | -4,805 | -11,537 | -12,865 | -21,545 | -57,685 | -79,763 | -133,579 | -357,647 | -398,815 | -667,895 | -1,788,235 | -11,087,057 | -55,435,285 |
