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 65,364,145, 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 | 65,364,145 | |
| -1 | -65,364,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,364,145.
Example:
1 x 65,364,145 = 65,364,145
and
-1 x -65,364,145 = 65,364,145
Notice both answers equal 65,364,145
With that explanation out of the way, let's continue. Next, we take the number 65,364,145 and divide it by 2:
65,364,145 ÷ 2 = 32,682,072.5
If the quotient is a whole number, then 2 and 32,682,072.5 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 | 65,364,145 | |
| -1 | -65,364,145 |
Now, we try dividing 65,364,145 by 3:
65,364,145 ÷ 3 = 21,788,048.3333
If the quotient is a whole number, then 3 and 21,788,048.3333 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 | 65,364,145 | |
| -1 | -65,364,145 |
Let's try dividing by 4:
65,364,145 ÷ 4 = 16,341,036.25
If the quotient is a whole number, then 4 and 16,341,036.25 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 | 65,364,145 | |
| -1 | 65,364,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 169,777 | 848,885 | 1,188,439 | 1,867,547 | 5,942,195 | 9,337,735 | 13,072,829 | 65,364,145 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -169,777 | -848,885 | -1,188,439 | -1,867,547 | -5,942,195 | -9,337,735 | -13,072,829 | -65,364,145 |
