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 65,582,965, 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 | 65,582,965 | |
| -1 | -65,582,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,582,965.
Example:
1 x 65,582,965 = 65,582,965
and
-1 x -65,582,965 = 65,582,965
Notice both answers equal 65,582,965
With that explanation out of the way, let's continue. Next, we take the number 65,582,965 and divide it by 2:
65,582,965 ÷ 2 = 32,791,482.5
If the quotient is a whole number, then 2 and 32,791,482.5 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 | 65,582,965 | |
| -1 | -65,582,965 |
Now, we try dividing 65,582,965 by 3:
65,582,965 ÷ 3 = 21,860,988.3333
If the quotient is a whole number, then 3 and 21,860,988.3333 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 | 65,582,965 | |
| -1 | -65,582,965 |
Let's try dividing by 4:
65,582,965 ÷ 4 = 16,395,741.25
If the quotient is a whole number, then 4 and 16,395,741.25 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 | 65,582,965 | |
| -1 | 65,582,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 98,621 | 493,105 | 690,347 | 1,873,799 | 3,451,735 | 9,368,995 | 13,116,593 | 65,582,965 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -98,621 | -493,105 | -690,347 | -1,873,799 | -3,451,735 | -9,368,995 | -13,116,593 | -65,582,965 |
