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 53,833,849, 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 | 53,833,849 | |
| -1 | -53,833,849 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,833,849.
Example:
1 x 53,833,849 = 53,833,849
and
-1 x -53,833,849 = 53,833,849
Notice both answers equal 53,833,849
With that explanation out of the way, let's continue. Next, we take the number 53,833,849 and divide it by 2:
53,833,849 ÷ 2 = 26,916,924.5
If the quotient is a whole number, then 2 and 26,916,924.5 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 | 53,833,849 | |
| -1 | -53,833,849 |
Now, we try dividing 53,833,849 by 3:
53,833,849 ÷ 3 = 17,944,616.3333
If the quotient is a whole number, then 3 and 17,944,616.3333 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 | 53,833,849 | |
| -1 | -53,833,849 |
Let's try dividing by 4:
53,833,849 ÷ 4 = 13,458,462.25
If the quotient is a whole number, then 4 and 13,458,462.25 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 | 53,833,849 | |
| -1 | 53,833,849 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 149 | 401 | 901 | 2,533 | 6,817 | 7,897 | 21,253 | 59,749 | 134,249 | 361,301 | 1,015,733 | 3,166,697 | 53,833,849 |
| -1 | -17 | -53 | -149 | -401 | -901 | -2,533 | -6,817 | -7,897 | -21,253 | -59,749 | -134,249 | -361,301 | -1,015,733 | -3,166,697 | -53,833,849 |
