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 30,446,195, 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 | 30,446,195 | |
| -1 | -30,446,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,446,195.
Example:
1 x 30,446,195 = 30,446,195
and
-1 x -30,446,195 = 30,446,195
Notice both answers equal 30,446,195
With that explanation out of the way, let's continue. Next, we take the number 30,446,195 and divide it by 2:
30,446,195 ÷ 2 = 15,223,097.5
If the quotient is a whole number, then 2 and 15,223,097.5 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 | 30,446,195 | |
| -1 | -30,446,195 |
Now, we try dividing 30,446,195 by 3:
30,446,195 ÷ 3 = 10,148,731.6667
If the quotient is a whole number, then 3 and 10,148,731.6667 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 | 30,446,195 | |
| -1 | -30,446,195 |
Let's try dividing by 4:
30,446,195 ÷ 4 = 7,611,548.75
If the quotient is a whole number, then 4 and 7,611,548.75 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 | 30,446,195 | |
| -1 | 30,446,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 137 | 169 | 263 | 685 | 845 | 1,315 | 1,781 | 3,419 | 8,905 | 17,095 | 23,153 | 36,031 | 44,447 | 115,765 | 180,155 | 222,235 | 468,403 | 2,342,015 | 6,089,239 | 30,446,195 |
| -1 | -5 | -13 | -65 | -137 | -169 | -263 | -685 | -845 | -1,315 | -1,781 | -3,419 | -8,905 | -17,095 | -23,153 | -36,031 | -44,447 | -115,765 | -180,155 | -222,235 | -468,403 | -2,342,015 | -6,089,239 | -30,446,195 |
