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 48,560,975, 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 | 48,560,975 | |
| -1 | -48,560,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,560,975.
Example:
1 x 48,560,975 = 48,560,975
and
-1 x -48,560,975 = 48,560,975
Notice both answers equal 48,560,975
With that explanation out of the way, let's continue. Next, we take the number 48,560,975 and divide it by 2:
48,560,975 ÷ 2 = 24,280,487.5
If the quotient is a whole number, then 2 and 24,280,487.5 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 | 48,560,975 | |
| -1 | -48,560,975 |
Now, we try dividing 48,560,975 by 3:
48,560,975 ÷ 3 = 16,186,991.6667
If the quotient is a whole number, then 3 and 16,186,991.6667 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 | 48,560,975 | |
| -1 | -48,560,975 |
Let's try dividing by 4:
48,560,975 ÷ 4 = 12,140,243.75
If the quotient is a whole number, then 4 and 12,140,243.75 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 | 48,560,975 | |
| -1 | 48,560,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 199 | 215 | 227 | 995 | 1,075 | 1,135 | 4,975 | 5,675 | 8,557 | 9,761 | 42,785 | 45,173 | 48,805 | 213,925 | 225,865 | 244,025 | 1,129,325 | 1,942,439 | 9,712,195 | 48,560,975 |
| -1 | -5 | -25 | -43 | -199 | -215 | -227 | -995 | -1,075 | -1,135 | -4,975 | -5,675 | -8,557 | -9,761 | -42,785 | -45,173 | -48,805 | -213,925 | -225,865 | -244,025 | -1,129,325 | -1,942,439 | -9,712,195 | -48,560,975 |
