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 50,778,355, 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 | 50,778,355 | |
| -1 | -50,778,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,778,355.
Example:
1 x 50,778,355 = 50,778,355
and
-1 x -50,778,355 = 50,778,355
Notice both answers equal 50,778,355
With that explanation out of the way, let's continue. Next, we take the number 50,778,355 and divide it by 2:
50,778,355 ÷ 2 = 25,389,177.5
If the quotient is a whole number, then 2 and 25,389,177.5 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 | 50,778,355 | |
| -1 | -50,778,355 |
Now, we try dividing 50,778,355 by 3:
50,778,355 ÷ 3 = 16,926,118.3333
If the quotient is a whole number, then 3 and 16,926,118.3333 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 | 50,778,355 | |
| -1 | -50,778,355 |
Let's try dividing by 4:
50,778,355 ÷ 4 = 12,694,588.75
If the quotient is a whole number, then 4 and 12,694,588.75 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 | 50,778,355 | |
| -1 | 50,778,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 373 | 1,433 | 1,865 | 7,087 | 7,165 | 27,227 | 35,435 | 136,135 | 534,509 | 2,672,545 | 10,155,671 | 50,778,355 |
| -1 | -5 | -19 | -95 | -373 | -1,433 | -1,865 | -7,087 | -7,165 | -27,227 | -35,435 | -136,135 | -534,509 | -2,672,545 | -10,155,671 | -50,778,355 |
