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 54,278,015, 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 | 54,278,015 | |
| -1 | -54,278,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,278,015.
Example:
1 x 54,278,015 = 54,278,015
and
-1 x -54,278,015 = 54,278,015
Notice both answers equal 54,278,015
With that explanation out of the way, let's continue. Next, we take the number 54,278,015 and divide it by 2:
54,278,015 ÷ 2 = 27,139,007.5
If the quotient is a whole number, then 2 and 27,139,007.5 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 | 54,278,015 | |
| -1 | -54,278,015 |
Now, we try dividing 54,278,015 by 3:
54,278,015 ÷ 3 = 18,092,671.6667
If the quotient is a whole number, then 3 and 18,092,671.6667 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 | 54,278,015 | |
| -1 | -54,278,015 |
Let's try dividing by 4:
54,278,015 ÷ 4 = 13,569,503.75
If the quotient is a whole number, then 4 and 13,569,503.75 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 | 54,278,015 | |
| -1 | 54,278,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 661 | 1,493 | 3,305 | 7,271 | 7,465 | 16,423 | 36,355 | 82,115 | 986,873 | 4,934,365 | 10,855,603 | 54,278,015 |
| -1 | -5 | -11 | -55 | -661 | -1,493 | -3,305 | -7,271 | -7,465 | -16,423 | -36,355 | -82,115 | -986,873 | -4,934,365 | -10,855,603 | -54,278,015 |
