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 53,456,249, 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 | 53,456,249 | |
| -1 | -53,456,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,456,249.
Example:
1 x 53,456,249 = 53,456,249
and
-1 x -53,456,249 = 53,456,249
Notice both answers equal 53,456,249
With that explanation out of the way, let's continue. Next, we take the number 53,456,249 and divide it by 2:
53,456,249 ÷ 2 = 26,728,124.5
If the quotient is a whole number, then 2 and 26,728,124.5 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 | 53,456,249 | |
| -1 | -53,456,249 |
Now, we try dividing 53,456,249 by 3:
53,456,249 ÷ 3 = 17,818,749.6667
If the quotient is a whole number, then 3 and 17,818,749.6667 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 | 53,456,249 | |
| -1 | -53,456,249 |
Let's try dividing by 4:
53,456,249 ÷ 4 = 13,364,062.25
If the quotient is a whole number, then 4 and 13,364,062.25 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 | 53,456,249 | |
| -1 | 53,456,249 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 3,619 | 14,771 | 103,397 | 162,481 | 694,237 | 1,137,367 | 4,859,659 | 7,636,607 | 53,456,249 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -3,619 | -14,771 | -103,397 | -162,481 | -694,237 | -1,137,367 | -4,859,659 | -7,636,607 | -53,456,249 |
