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 65,774,653, 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 | 65,774,653 | |
| -1 | -65,774,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,774,653.
Example:
1 x 65,774,653 = 65,774,653
and
-1 x -65,774,653 = 65,774,653
Notice both answers equal 65,774,653
With that explanation out of the way, let's continue. Next, we take the number 65,774,653 and divide it by 2:
65,774,653 ÷ 2 = 32,887,326.5
If the quotient is a whole number, then 2 and 32,887,326.5 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 | 65,774,653 | |
| -1 | -65,774,653 |
Now, we try dividing 65,774,653 by 3:
65,774,653 ÷ 3 = 21,924,884.3333
If the quotient is a whole number, then 3 and 21,924,884.3333 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 | 65,774,653 | |
| -1 | -65,774,653 |
Let's try dividing by 4:
65,774,653 ÷ 4 = 16,443,663.25
If the quotient is a whole number, then 4 and 16,443,663.25 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 | 65,774,653 | |
| -1 | 65,774,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 61 | 217 | 427 | 1,891 | 4,969 | 13,237 | 34,783 | 154,039 | 303,109 | 1,078,273 | 2,121,763 | 9,396,379 | 65,774,653 |
| -1 | -7 | -31 | -61 | -217 | -427 | -1,891 | -4,969 | -13,237 | -34,783 | -154,039 | -303,109 | -1,078,273 | -2,121,763 | -9,396,379 | -65,774,653 |
