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 49,765,135, 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 | 49,765,135 | |
| -1 | -49,765,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,765,135.
Example:
1 x 49,765,135 = 49,765,135
and
-1 x -49,765,135 = 49,765,135
Notice both answers equal 49,765,135
With that explanation out of the way, let's continue. Next, we take the number 49,765,135 and divide it by 2:
49,765,135 ÷ 2 = 24,882,567.5
If the quotient is a whole number, then 2 and 24,882,567.5 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 | 49,765,135 | |
| -1 | -49,765,135 |
Now, we try dividing 49,765,135 by 3:
49,765,135 ÷ 3 = 16,588,378.3333
If the quotient is a whole number, then 3 and 16,588,378.3333 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 | 49,765,135 | |
| -1 | -49,765,135 |
Let's try dividing by 4:
49,765,135 ÷ 4 = 12,441,283.75
If the quotient is a whole number, then 4 and 12,441,283.75 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 | 49,765,135 | |
| -1 | 49,765,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 229 | 245 | 887 | 1,145 | 1,603 | 4,435 | 6,209 | 8,015 | 11,221 | 31,045 | 43,463 | 56,105 | 203,123 | 217,315 | 1,015,615 | 1,421,861 | 7,109,305 | 9,953,027 | 49,765,135 |
| -1 | -5 | -7 | -35 | -49 | -229 | -245 | -887 | -1,145 | -1,603 | -4,435 | -6,209 | -8,015 | -11,221 | -31,045 | -43,463 | -56,105 | -203,123 | -217,315 | -1,015,615 | -1,421,861 | -7,109,305 | -9,953,027 | -49,765,135 |
