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 49,815,623, 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 | 49,815,623 | |
| -1 | -49,815,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,815,623.
Example:
1 x 49,815,623 = 49,815,623
and
-1 x -49,815,623 = 49,815,623
Notice both answers equal 49,815,623
With that explanation out of the way, let's continue. Next, we take the number 49,815,623 and divide it by 2:
49,815,623 ÷ 2 = 24,907,811.5
If the quotient is a whole number, then 2 and 24,907,811.5 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 | 49,815,623 | |
| -1 | -49,815,623 |
Now, we try dividing 49,815,623 by 3:
49,815,623 ÷ 3 = 16,605,207.6667
If the quotient is a whole number, then 3 and 16,605,207.6667 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 | 49,815,623 | |
| -1 | -49,815,623 |
Let's try dividing by 4:
49,815,623 ÷ 4 = 12,453,905.75
If the quotient is a whole number, then 4 and 12,453,905.75 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 | 49,815,623 | |
| -1 | 49,815,623 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 127 | 143 | 169 | 211 | 1,397 | 1,651 | 1,859 | 2,321 | 2,743 | 18,161 | 21,463 | 26,797 | 30,173 | 35,659 | 236,093 | 294,767 | 348,361 | 392,249 | 3,831,971 | 4,528,693 | 49,815,623 |
| -1 | -11 | -13 | -127 | -143 | -169 | -211 | -1,397 | -1,651 | -1,859 | -2,321 | -2,743 | -18,161 | -21,463 | -26,797 | -30,173 | -35,659 | -236,093 | -294,767 | -348,361 | -392,249 | -3,831,971 | -4,528,693 | -49,815,623 |
