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 49,765,123, 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 | 49,765,123 | |
| -1 | -49,765,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,765,123.
Example:
1 x 49,765,123 = 49,765,123
and
-1 x -49,765,123 = 49,765,123
Notice both answers equal 49,765,123
With that explanation out of the way, let's continue. Next, we take the number 49,765,123 and divide it by 2:
49,765,123 ÷ 2 = 24,882,561.5
If the quotient is a whole number, then 2 and 24,882,561.5 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 | 49,765,123 | |
| -1 | -49,765,123 |
Now, we try dividing 49,765,123 by 3:
49,765,123 ÷ 3 = 16,588,374.3333
If the quotient is a whole number, then 3 and 16,588,374.3333 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 | 49,765,123 | |
| -1 | -49,765,123 |
Let's try dividing by 4:
49,765,123 ÷ 4 = 12,441,280.75
If the quotient is a whole number, then 4 and 12,441,280.75 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 | 49,765,123 | |
| -1 | 49,765,123 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 263 | 433 | 437 | 4,997 | 6,049 | 8,227 | 9,959 | 113,879 | 114,931 | 189,221 | 2,163,701 | 2,619,217 | 49,765,123 |
| -1 | -19 | -23 | -263 | -433 | -437 | -4,997 | -6,049 | -8,227 | -9,959 | -113,879 | -114,931 | -189,221 | -2,163,701 | -2,619,217 | -49,765,123 |
