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 48,724,907, 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 | 48,724,907 | |
| -1 | -48,724,907 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,724,907.
Example:
1 x 48,724,907 = 48,724,907
and
-1 x -48,724,907 = 48,724,907
Notice both answers equal 48,724,907
With that explanation out of the way, let's continue. Next, we take the number 48,724,907 and divide it by 2:
48,724,907 ÷ 2 = 24,362,453.5
If the quotient is a whole number, then 2 and 24,362,453.5 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 | 48,724,907 | |
| -1 | -48,724,907 |
Now, we try dividing 48,724,907 by 3:
48,724,907 ÷ 3 = 16,241,635.6667
If the quotient is a whole number, then 3 and 16,241,635.6667 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 | 48,724,907 | |
| -1 | -48,724,907 |
Let's try dividing by 4:
48,724,907 ÷ 4 = 12,181,226.75
If the quotient is a whole number, then 4 and 12,181,226.75 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 | 48,724,907 | |
| -1 | 48,724,907 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 37,223 | 260,561 | 409,453 | 632,791 | 2,866,171 | 4,429,537 | 6,960,701 | 48,724,907 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -37,223 | -260,561 | -409,453 | -632,791 | -2,866,171 | -4,429,537 | -6,960,701 | -48,724,907 |
