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 55,414,475, 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 | 55,414,475 | |
| -1 | -55,414,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,414,475.
Example:
1 x 55,414,475 = 55,414,475
and
-1 x -55,414,475 = 55,414,475
Notice both answers equal 55,414,475
With that explanation out of the way, let's continue. Next, we take the number 55,414,475 and divide it by 2:
55,414,475 ÷ 2 = 27,707,237.5
If the quotient is a whole number, then 2 and 27,707,237.5 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 | 55,414,475 | |
| -1 | -55,414,475 |
Now, we try dividing 55,414,475 by 3:
55,414,475 ÷ 3 = 18,471,491.6667
If the quotient is a whole number, then 3 and 18,471,491.6667 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 | 55,414,475 | |
| -1 | -55,414,475 |
Let's try dividing by 4:
55,414,475 ÷ 4 = 13,853,618.75
If the quotient is a whole number, then 4 and 13,853,618.75 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 | 55,414,475 | |
| -1 | 55,414,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 25 | 85 | 115 | 391 | 425 | 575 | 1,955 | 5,669 | 9,775 | 28,345 | 96,373 | 130,387 | 141,725 | 481,865 | 651,935 | 2,216,579 | 2,409,325 | 3,259,675 | 11,082,895 | 55,414,475 |
| -1 | -5 | -17 | -23 | -25 | -85 | -115 | -391 | -425 | -575 | -1,955 | -5,669 | -9,775 | -28,345 | -96,373 | -130,387 | -141,725 | -481,865 | -651,935 | -2,216,579 | -2,409,325 | -3,259,675 | -11,082,895 | -55,414,475 |
