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 64,328,803, 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 | 64,328,803 | |
| -1 | -64,328,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,328,803.
Example:
1 x 64,328,803 = 64,328,803
and
-1 x -64,328,803 = 64,328,803
Notice both answers equal 64,328,803
With that explanation out of the way, let's continue. Next, we take the number 64,328,803 and divide it by 2:
64,328,803 ÷ 2 = 32,164,401.5
If the quotient is a whole number, then 2 and 32,164,401.5 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 | 64,328,803 | |
| -1 | -64,328,803 |
Now, we try dividing 64,328,803 by 3:
64,328,803 ÷ 3 = 21,442,934.3333
If the quotient is a whole number, then 3 and 21,442,934.3333 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 | 64,328,803 | |
| -1 | -64,328,803 |
Let's try dividing by 4:
64,328,803 ÷ 4 = 16,082,200.75
If the quotient is a whole number, then 4 and 16,082,200.75 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 | 64,328,803 | |
| -1 | 64,328,803 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 53 | 77 | 121 | 371 | 583 | 847 | 1,433 | 4,081 | 6,413 | 10,031 | 15,763 | 44,891 | 75,949 | 110,341 | 173,393 | 531,643 | 835,439 | 1,213,751 | 5,848,073 | 9,189,829 | 64,328,803 |
| -1 | -7 | -11 | -53 | -77 | -121 | -371 | -583 | -847 | -1,433 | -4,081 | -6,413 | -10,031 | -15,763 | -44,891 | -75,949 | -110,341 | -173,393 | -531,643 | -835,439 | -1,213,751 | -5,848,073 | -9,189,829 | -64,328,803 |
