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 55,562,255, 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 | 55,562,255 | |
| -1 | -55,562,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,562,255.
Example:
1 x 55,562,255 = 55,562,255
and
-1 x -55,562,255 = 55,562,255
Notice both answers equal 55,562,255
With that explanation out of the way, let's continue. Next, we take the number 55,562,255 and divide it by 2:
55,562,255 ÷ 2 = 27,781,127.5
If the quotient is a whole number, then 2 and 27,781,127.5 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 | 55,562,255 | |
| -1 | -55,562,255 |
Now, we try dividing 55,562,255 by 3:
55,562,255 ÷ 3 = 18,520,751.6667
If the quotient is a whole number, then 3 and 18,520,751.6667 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 | 55,562,255 | |
| -1 | -55,562,255 |
Let's try dividing by 4:
55,562,255 ÷ 4 = 13,890,563.75
If the quotient is a whole number, then 4 and 13,890,563.75 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 | 55,562,255 | |
| -1 | 55,562,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 89 | 445 | 623 | 3,115 | 17,837 | 89,185 | 124,859 | 624,295 | 1,587,493 | 7,937,465 | 11,112,451 | 55,562,255 |
| -1 | -5 | -7 | -35 | -89 | -445 | -623 | -3,115 | -17,837 | -89,185 | -124,859 | -624,295 | -1,587,493 | -7,937,465 | -11,112,451 | -55,562,255 |
