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 65,504,245, 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 | 65,504,245 | |
| -1 | -65,504,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,504,245.
Example:
1 x 65,504,245 = 65,504,245
and
-1 x -65,504,245 = 65,504,245
Notice both answers equal 65,504,245
With that explanation out of the way, let's continue. Next, we take the number 65,504,245 and divide it by 2:
65,504,245 ÷ 2 = 32,752,122.5
If the quotient is a whole number, then 2 and 32,752,122.5 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 | 65,504,245 | |
| -1 | -65,504,245 |
Now, we try dividing 65,504,245 by 3:
65,504,245 ÷ 3 = 21,834,748.3333
If the quotient is a whole number, then 3 and 21,834,748.3333 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 | 65,504,245 | |
| -1 | -65,504,245 |
Let's try dividing by 4:
65,504,245 ÷ 4 = 16,376,061.25
If the quotient is a whole number, then 4 and 16,376,061.25 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 | 65,504,245 | |
| -1 | 65,504,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 71 | 185 | 355 | 2,627 | 4,987 | 13,135 | 24,935 | 184,519 | 354,077 | 922,595 | 1,770,385 | 13,100,849 | 65,504,245 |
| -1 | -5 | -37 | -71 | -185 | -355 | -2,627 | -4,987 | -13,135 | -24,935 | -184,519 | -354,077 | -922,595 | -1,770,385 | -13,100,849 | -65,504,245 |
