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 54,221,245, 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 | 54,221,245 | |
| -1 | -54,221,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,221,245.
Example:
1 x 54,221,245 = 54,221,245
and
-1 x -54,221,245 = 54,221,245
Notice both answers equal 54,221,245
With that explanation out of the way, let's continue. Next, we take the number 54,221,245 and divide it by 2:
54,221,245 ÷ 2 = 27,110,622.5
If the quotient is a whole number, then 2 and 27,110,622.5 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 | 54,221,245 | |
| -1 | -54,221,245 |
Now, we try dividing 54,221,245 by 3:
54,221,245 ÷ 3 = 18,073,748.3333
If the quotient is a whole number, then 3 and 18,073,748.3333 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 | 54,221,245 | |
| -1 | -54,221,245 |
Let's try dividing by 4:
54,221,245 ÷ 4 = 13,555,311.25
If the quotient is a whole number, then 4 and 13,555,311.25 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 | 54,221,245 | |
| -1 | 54,221,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 49,069 | 245,345 | 637,897 | 834,173 | 3,189,485 | 4,170,865 | 10,844,249 | 54,221,245 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -49,069 | -245,345 | -637,897 | -834,173 | -3,189,485 | -4,170,865 | -10,844,249 | -54,221,245 |
