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 53,050,217, 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 | 53,050,217 | |
| -1 | -53,050,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,050,217.
Example:
1 x 53,050,217 = 53,050,217
and
-1 x -53,050,217 = 53,050,217
Notice both answers equal 53,050,217
With that explanation out of the way, let's continue. Next, we take the number 53,050,217 and divide it by 2:
53,050,217 ÷ 2 = 26,525,108.5
If the quotient is a whole number, then 2 and 26,525,108.5 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 | 53,050,217 | |
| -1 | -53,050,217 |
Now, we try dividing 53,050,217 by 3:
53,050,217 ÷ 3 = 17,683,405.6667
If the quotient is a whole number, then 3 and 17,683,405.6667 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 | 53,050,217 | |
| -1 | -53,050,217 |
Let's try dividing by 4:
53,050,217 ÷ 4 = 13,262,554.25
If the quotient is a whole number, then 4 and 13,262,554.25 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 | 53,050,217 | |
| -1 | 53,050,217 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 367 | 773 | 4,037 | 6,239 | 8,503 | 13,141 | 68,629 | 144,551 | 283,691 | 3,120,601 | 4,822,747 | 53,050,217 |
| -1 | -11 | -17 | -187 | -367 | -773 | -4,037 | -6,239 | -8,503 | -13,141 | -68,629 | -144,551 | -283,691 | -3,120,601 | -4,822,747 | -53,050,217 |
