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 49,148,699, 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 | 49,148,699 | |
| -1 | -49,148,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,148,699.
Example:
1 x 49,148,699 = 49,148,699
and
-1 x -49,148,699 = 49,148,699
Notice both answers equal 49,148,699
With that explanation out of the way, let's continue. Next, we take the number 49,148,699 and divide it by 2:
49,148,699 ÷ 2 = 24,574,349.5
If the quotient is a whole number, then 2 and 24,574,349.5 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 | 49,148,699 | |
| -1 | -49,148,699 |
Now, we try dividing 49,148,699 by 3:
49,148,699 ÷ 3 = 16,382,899.6667
If the quotient is a whole number, then 3 and 16,382,899.6667 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 | 49,148,699 | |
| -1 | -49,148,699 |
Let's try dividing by 4:
49,148,699 ÷ 4 = 12,287,174.75
If the quotient is a whole number, then 4 and 12,287,174.75 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 | 49,148,699 | |
| -1 | 49,148,699 |
If you did it right, you will end up with this table:
| 1 | 43 | 47 | 83 | 293 | 2,021 | 3,569 | 3,901 | 12,599 | 13,771 | 24,319 | 167,743 | 592,153 | 1,045,717 | 1,142,993 | 49,148,699 |
| -1 | -43 | -47 | -83 | -293 | -2,021 | -3,569 | -3,901 | -12,599 | -13,771 | -24,319 | -167,743 | -592,153 | -1,045,717 | -1,142,993 | -49,148,699 |
