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 55,577,753, 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 | 55,577,753 | |
| -1 | -55,577,753 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,577,753.
Example:
1 x 55,577,753 = 55,577,753
and
-1 x -55,577,753 = 55,577,753
Notice both answers equal 55,577,753
With that explanation out of the way, let's continue. Next, we take the number 55,577,753 and divide it by 2:
55,577,753 ÷ 2 = 27,788,876.5
If the quotient is a whole number, then 2 and 27,788,876.5 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 | 55,577,753 | |
| -1 | -55,577,753 |
Now, we try dividing 55,577,753 by 3:
55,577,753 ÷ 3 = 18,525,917.6667
If the quotient is a whole number, then 3 and 18,525,917.6667 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 | 55,577,753 | |
| -1 | -55,577,753 |
Let's try dividing by 4:
55,577,753 ÷ 4 = 13,894,438.25
If the quotient is a whole number, then 4 and 13,894,438.25 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 | 55,577,753 | |
| -1 | 55,577,753 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 191 | 1,337 | 2,101 | 3,779 | 14,707 | 26,453 | 41,569 | 290,983 | 721,789 | 5,052,523 | 7,939,679 | 55,577,753 |
| -1 | -7 | -11 | -77 | -191 | -1,337 | -2,101 | -3,779 | -14,707 | -26,453 | -41,569 | -290,983 | -721,789 | -5,052,523 | -7,939,679 | -55,577,753 |
