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 54,786,125, 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 | 54,786,125 | |
| -1 | -54,786,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,786,125.
Example:
1 x 54,786,125 = 54,786,125
and
-1 x -54,786,125 = 54,786,125
Notice both answers equal 54,786,125
With that explanation out of the way, let's continue. Next, we take the number 54,786,125 and divide it by 2:
54,786,125 ÷ 2 = 27,393,062.5
If the quotient is a whole number, then 2 and 27,393,062.5 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 | 54,786,125 | |
| -1 | -54,786,125 |
Now, we try dividing 54,786,125 by 3:
54,786,125 ÷ 3 = 18,262,041.6667
If the quotient is a whole number, then 3 and 18,262,041.6667 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 | 54,786,125 | |
| -1 | -54,786,125 |
Let's try dividing by 4:
54,786,125 ÷ 4 = 13,696,531.25
If the quotient is a whole number, then 4 and 13,696,531.25 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 | 54,786,125 | |
| -1 | 54,786,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 109 | 125 | 545 | 2,725 | 4,021 | 13,625 | 20,105 | 100,525 | 438,289 | 502,625 | 2,191,445 | 10,957,225 | 54,786,125 |
| -1 | -5 | -25 | -109 | -125 | -545 | -2,725 | -4,021 | -13,625 | -20,105 | -100,525 | -438,289 | -502,625 | -2,191,445 | -10,957,225 | -54,786,125 |
