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 53,805,241, 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 | 53,805,241 | |
| -1 | -53,805,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,805,241.
Example:
1 x 53,805,241 = 53,805,241
and
-1 x -53,805,241 = 53,805,241
Notice both answers equal 53,805,241
With that explanation out of the way, let's continue. Next, we take the number 53,805,241 and divide it by 2:
53,805,241 ÷ 2 = 26,902,620.5
If the quotient is a whole number, then 2 and 26,902,620.5 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 | 53,805,241 | |
| -1 | -53,805,241 |
Now, we try dividing 53,805,241 by 3:
53,805,241 ÷ 3 = 17,935,080.3333
If the quotient is a whole number, then 3 and 17,935,080.3333 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 | 53,805,241 | |
| -1 | -53,805,241 |
Let's try dividing by 4:
53,805,241 ÷ 4 = 13,451,310.25
If the quotient is a whole number, then 4 and 13,451,310.25 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 | 53,805,241 | |
| -1 | 53,805,241 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 149 | 553 | 653 | 1,043 | 4,571 | 11,771 | 51,587 | 82,397 | 97,297 | 361,109 | 681,079 | 7,686,463 | 53,805,241 |
| -1 | -7 | -79 | -149 | -553 | -653 | -1,043 | -4,571 | -11,771 | -51,587 | -82,397 | -97,297 | -361,109 | -681,079 | -7,686,463 | -53,805,241 |
