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 53,500,205, 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 | 53,500,205 | |
| -1 | -53,500,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,500,205.
Example:
1 x 53,500,205 = 53,500,205
and
-1 x -53,500,205 = 53,500,205
Notice both answers equal 53,500,205
With that explanation out of the way, let's continue. Next, we take the number 53,500,205 and divide it by 2:
53,500,205 ÷ 2 = 26,750,102.5
If the quotient is a whole number, then 2 and 26,750,102.5 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 | 53,500,205 | |
| -1 | -53,500,205 |
Now, we try dividing 53,500,205 by 3:
53,500,205 ÷ 3 = 17,833,401.6667
If the quotient is a whole number, then 3 and 17,833,401.6667 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 | 53,500,205 | |
| -1 | -53,500,205 |
Let's try dividing by 4:
53,500,205 ÷ 4 = 13,375,051.25
If the quotient is a whole number, then 4 and 13,375,051.25 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 | 53,500,205 | |
| -1 | 53,500,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 505 | 1,111 | 5,555 | 9,631 | 48,155 | 105,941 | 529,705 | 972,731 | 4,863,655 | 10,700,041 | 53,500,205 |
| -1 | -5 | -11 | -55 | -101 | -505 | -1,111 | -5,555 | -9,631 | -48,155 | -105,941 | -529,705 | -972,731 | -4,863,655 | -10,700,041 | -53,500,205 |
