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 55,710,413, 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 | 55,710,413 | |
| -1 | -55,710,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,710,413.
Example:
1 x 55,710,413 = 55,710,413
and
-1 x -55,710,413 = 55,710,413
Notice both answers equal 55,710,413
With that explanation out of the way, let's continue. Next, we take the number 55,710,413 and divide it by 2:
55,710,413 ÷ 2 = 27,855,206.5
If the quotient is a whole number, then 2 and 27,855,206.5 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 | 55,710,413 | |
| -1 | -55,710,413 |
Now, we try dividing 55,710,413 by 3:
55,710,413 ÷ 3 = 18,570,137.6667
If the quotient is a whole number, then 3 and 18,570,137.6667 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 | 55,710,413 | |
| -1 | -55,710,413 |
Let's try dividing by 4:
55,710,413 ÷ 4 = 13,927,603.25
If the quotient is a whole number, then 4 and 13,927,603.25 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 | 55,710,413 | |
| -1 | 55,710,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 43 | 209 | 473 | 817 | 6,199 | 8,987 | 68,189 | 117,781 | 266,557 | 1,295,591 | 2,932,127 | 5,064,583 | 55,710,413 |
| -1 | -11 | -19 | -43 | -209 | -473 | -817 | -6,199 | -8,987 | -68,189 | -117,781 | -266,557 | -1,295,591 | -2,932,127 | -5,064,583 | -55,710,413 |
