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 55,338,773, 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 | 55,338,773 | |
| -1 | -55,338,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,338,773.
Example:
1 x 55,338,773 = 55,338,773
and
-1 x -55,338,773 = 55,338,773
Notice both answers equal 55,338,773
With that explanation out of the way, let's continue. Next, we take the number 55,338,773 and divide it by 2:
55,338,773 ÷ 2 = 27,669,386.5
If the quotient is a whole number, then 2 and 27,669,386.5 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 | 55,338,773 | |
| -1 | -55,338,773 |
Now, we try dividing 55,338,773 by 3:
55,338,773 ÷ 3 = 18,446,257.6667
If the quotient is a whole number, then 3 and 18,446,257.6667 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 | 55,338,773 | |
| -1 | -55,338,773 |
Let's try dividing by 4:
55,338,773 ÷ 4 = 13,834,693.25
If the quotient is a whole number, then 4 and 13,834,693.25 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 | 55,338,773 | |
| -1 | 55,338,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 61 | 133 | 359 | 361 | 427 | 1,159 | 2,513 | 2,527 | 6,821 | 8,113 | 21,899 | 22,021 | 47,747 | 129,599 | 153,293 | 154,147 | 416,081 | 907,193 | 2,912,567 | 7,905,539 | 55,338,773 |
| -1 | -7 | -19 | -61 | -133 | -359 | -361 | -427 | -1,159 | -2,513 | -2,527 | -6,821 | -8,113 | -21,899 | -22,021 | -47,747 | -129,599 | -153,293 | -154,147 | -416,081 | -907,193 | -2,912,567 | -7,905,539 | -55,338,773 |
