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 56,354,255, 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 | 56,354,255 | |
| -1 | -56,354,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,354,255.
Example:
1 x 56,354,255 = 56,354,255
and
-1 x -56,354,255 = 56,354,255
Notice both answers equal 56,354,255
With that explanation out of the way, let's continue. Next, we take the number 56,354,255 and divide it by 2:
56,354,255 ÷ 2 = 28,177,127.5
If the quotient is a whole number, then 2 and 28,177,127.5 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 | 56,354,255 | |
| -1 | -56,354,255 |
Now, we try dividing 56,354,255 by 3:
56,354,255 ÷ 3 = 18,784,751.6667
If the quotient is a whole number, then 3 and 18,784,751.6667 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 | 56,354,255 | |
| -1 | -56,354,255 |
Let's try dividing by 4:
56,354,255 ÷ 4 = 14,088,563.75
If the quotient is a whole number, then 4 and 14,088,563.75 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 | 56,354,255 | |
| -1 | 56,354,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 79 | 115 | 395 | 1,817 | 6,203 | 9,085 | 31,015 | 142,669 | 490,037 | 713,345 | 2,450,185 | 11,270,851 | 56,354,255 |
| -1 | -5 | -23 | -79 | -115 | -395 | -1,817 | -6,203 | -9,085 | -31,015 | -142,669 | -490,037 | -713,345 | -2,450,185 | -11,270,851 | -56,354,255 |
