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 64,225,235, 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 | 64,225,235 | |
| -1 | -64,225,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,225,235.
Example:
1 x 64,225,235 = 64,225,235
and
-1 x -64,225,235 = 64,225,235
Notice both answers equal 64,225,235
With that explanation out of the way, let's continue. Next, we take the number 64,225,235 and divide it by 2:
64,225,235 ÷ 2 = 32,112,617.5
If the quotient is a whole number, then 2 and 32,112,617.5 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 | 64,225,235 | |
| -1 | -64,225,235 |
Now, we try dividing 64,225,235 by 3:
64,225,235 ÷ 3 = 21,408,411.6667
If the quotient is a whole number, then 3 and 21,408,411.6667 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 | 64,225,235 | |
| -1 | -64,225,235 |
Let's try dividing by 4:
64,225,235 ÷ 4 = 16,056,308.75
If the quotient is a whole number, then 4 and 16,056,308.75 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 | 64,225,235 | |
| -1 | 64,225,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 211 | 1,055 | 3,581 | 3,587 | 17,905 | 17,935 | 60,877 | 304,385 | 755,591 | 3,777,955 | 12,845,047 | 64,225,235 |
| -1 | -5 | -17 | -85 | -211 | -1,055 | -3,581 | -3,587 | -17,905 | -17,935 | -60,877 | -304,385 | -755,591 | -3,777,955 | -12,845,047 | -64,225,235 |
