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 54,241,445, 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 | 54,241,445 | |
| -1 | -54,241,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,241,445.
Example:
1 x 54,241,445 = 54,241,445
and
-1 x -54,241,445 = 54,241,445
Notice both answers equal 54,241,445
With that explanation out of the way, let's continue. Next, we take the number 54,241,445 and divide it by 2:
54,241,445 ÷ 2 = 27,120,722.5
If the quotient is a whole number, then 2 and 27,120,722.5 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 | 54,241,445 | |
| -1 | -54,241,445 |
Now, we try dividing 54,241,445 by 3:
54,241,445 ÷ 3 = 18,080,481.6667
If the quotient is a whole number, then 3 and 18,080,481.6667 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 | 54,241,445 | |
| -1 | -54,241,445 |
Let's try dividing by 4:
54,241,445 ÷ 4 = 13,560,361.25
If the quotient is a whole number, then 4 and 13,560,361.25 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 | 54,241,445 | |
| -1 | 54,241,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 449 | 653 | 2,245 | 3,265 | 16,613 | 24,161 | 83,065 | 120,805 | 293,197 | 1,465,985 | 10,848,289 | 54,241,445 |
| -1 | -5 | -37 | -185 | -449 | -653 | -2,245 | -3,265 | -16,613 | -24,161 | -83,065 | -120,805 | -293,197 | -1,465,985 | -10,848,289 | -54,241,445 |
