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 53,606,105, 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 | 53,606,105 | |
| -1 | -53,606,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,606,105.
Example:
1 x 53,606,105 = 53,606,105
and
-1 x -53,606,105 = 53,606,105
Notice both answers equal 53,606,105
With that explanation out of the way, let's continue. Next, we take the number 53,606,105 and divide it by 2:
53,606,105 ÷ 2 = 26,803,052.5
If the quotient is a whole number, then 2 and 26,803,052.5 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 | 53,606,105 | |
| -1 | -53,606,105 |
Now, we try dividing 53,606,105 by 3:
53,606,105 ÷ 3 = 17,868,701.6667
If the quotient is a whole number, then 3 and 17,868,701.6667 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 | 53,606,105 | |
| -1 | -53,606,105 |
Let's try dividing by 4:
53,606,105 ÷ 4 = 13,401,526.25
If the quotient is a whole number, then 4 and 13,401,526.25 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 | 53,606,105 | |
| -1 | 53,606,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 823 | 1,861 | 4,115 | 5,761 | 9,305 | 13,027 | 28,805 | 65,135 | 1,531,603 | 7,658,015 | 10,721,221 | 53,606,105 |
| -1 | -5 | -7 | -35 | -823 | -1,861 | -4,115 | -5,761 | -9,305 | -13,027 | -28,805 | -65,135 | -1,531,603 | -7,658,015 | -10,721,221 | -53,606,105 |
