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 54,611,245, 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 | 54,611,245 | |
| -1 | -54,611,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,611,245.
Example:
1 x 54,611,245 = 54,611,245
and
-1 x -54,611,245 = 54,611,245
Notice both answers equal 54,611,245
With that explanation out of the way, let's continue. Next, we take the number 54,611,245 and divide it by 2:
54,611,245 ÷ 2 = 27,305,622.5
If the quotient is a whole number, then 2 and 27,305,622.5 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 | 54,611,245 | |
| -1 | -54,611,245 |
Now, we try dividing 54,611,245 by 3:
54,611,245 ÷ 3 = 18,203,748.3333
If the quotient is a whole number, then 3 and 18,203,748.3333 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 | 54,611,245 | |
| -1 | -54,611,245 |
Let's try dividing by 4:
54,611,245 ÷ 4 = 13,652,811.25
If the quotient is a whole number, then 4 and 13,652,811.25 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 | 54,611,245 | |
| -1 | 54,611,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 541 | 1,553 | 2,705 | 7,033 | 7,765 | 20,189 | 35,165 | 100,945 | 840,173 | 4,200,865 | 10,922,249 | 54,611,245 |
| -1 | -5 | -13 | -65 | -541 | -1,553 | -2,705 | -7,033 | -7,765 | -20,189 | -35,165 | -100,945 | -840,173 | -4,200,865 | -10,922,249 | -54,611,245 |
