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 53,551,469, 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 | 53,551,469 | |
| -1 | -53,551,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,551,469.
Example:
1 x 53,551,469 = 53,551,469
and
-1 x -53,551,469 = 53,551,469
Notice both answers equal 53,551,469
With that explanation out of the way, let's continue. Next, we take the number 53,551,469 and divide it by 2:
53,551,469 ÷ 2 = 26,775,734.5
If the quotient is a whole number, then 2 and 26,775,734.5 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 | 53,551,469 | |
| -1 | -53,551,469 |
Now, we try dividing 53,551,469 by 3:
53,551,469 ÷ 3 = 17,850,489.6667
If the quotient is a whole number, then 3 and 17,850,489.6667 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 | 53,551,469 | |
| -1 | -53,551,469 |
Let's try dividing by 4:
53,551,469 ÷ 4 = 13,387,867.25
If the quotient is a whole number, then 4 and 13,387,867.25 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 | 53,551,469 | |
| -1 | 53,551,469 |
If you did it right, you will end up with this table:
| 1 | 37 | 43 | 97 | 347 | 1,591 | 3,589 | 4,171 | 12,839 | 14,921 | 33,659 | 154,327 | 552,077 | 1,245,383 | 1,447,337 | 53,551,469 |
| -1 | -37 | -43 | -97 | -347 | -1,591 | -3,589 | -4,171 | -12,839 | -14,921 | -33,659 | -154,327 | -552,077 | -1,245,383 | -1,447,337 | -53,551,469 |
