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 64,503,035, 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 | 64,503,035 | |
| -1 | -64,503,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,503,035.
Example:
1 x 64,503,035 = 64,503,035
and
-1 x -64,503,035 = 64,503,035
Notice both answers equal 64,503,035
With that explanation out of the way, let's continue. Next, we take the number 64,503,035 and divide it by 2:
64,503,035 ÷ 2 = 32,251,517.5
If the quotient is a whole number, then 2 and 32,251,517.5 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 | 64,503,035 | |
| -1 | -64,503,035 |
Now, we try dividing 64,503,035 by 3:
64,503,035 ÷ 3 = 21,501,011.6667
If the quotient is a whole number, then 3 and 21,501,011.6667 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 | 64,503,035 | |
| -1 | -64,503,035 |
Let's try dividing by 4:
64,503,035 ÷ 4 = 16,125,758.75
If the quotient is a whole number, then 4 and 16,125,758.75 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 | 64,503,035 | |
| -1 | 64,503,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 83 | 235 | 415 | 3,307 | 3,901 | 16,535 | 19,505 | 155,429 | 274,481 | 777,145 | 1,372,405 | 12,900,607 | 64,503,035 |
| -1 | -5 | -47 | -83 | -235 | -415 | -3,307 | -3,901 | -16,535 | -19,505 | -155,429 | -274,481 | -777,145 | -1,372,405 | -12,900,607 | -64,503,035 |
