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 48,451,385, 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 | 48,451,385 | |
| -1 | -48,451,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,451,385.
Example:
1 x 48,451,385 = 48,451,385
and
-1 x -48,451,385 = 48,451,385
Notice both answers equal 48,451,385
With that explanation out of the way, let's continue. Next, we take the number 48,451,385 and divide it by 2:
48,451,385 ÷ 2 = 24,225,692.5
If the quotient is a whole number, then 2 and 24,225,692.5 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 | 48,451,385 | |
| -1 | -48,451,385 |
Now, we try dividing 48,451,385 by 3:
48,451,385 ÷ 3 = 16,150,461.6667
If the quotient is a whole number, then 3 and 16,150,461.6667 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 | 48,451,385 | |
| -1 | -48,451,385 |
Let's try dividing by 4:
48,451,385 ÷ 4 = 12,112,846.25
If the quotient is a whole number, then 4 and 12,112,846.25 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 | 48,451,385 | |
| -1 | 48,451,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 67 | 305 | 335 | 2,371 | 4,087 | 11,855 | 20,435 | 144,631 | 158,857 | 723,155 | 794,285 | 9,690,277 | 48,451,385 |
| -1 | -5 | -61 | -67 | -305 | -335 | -2,371 | -4,087 | -11,855 | -20,435 | -144,631 | -158,857 | -723,155 | -794,285 | -9,690,277 | -48,451,385 |
