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 65,401,235, 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 | 65,401,235 | |
| -1 | -65,401,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,401,235.
Example:
1 x 65,401,235 = 65,401,235
and
-1 x -65,401,235 = 65,401,235
Notice both answers equal 65,401,235
With that explanation out of the way, let's continue. Next, we take the number 65,401,235 and divide it by 2:
65,401,235 ÷ 2 = 32,700,617.5
If the quotient is a whole number, then 2 and 32,700,617.5 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 | 65,401,235 | |
| -1 | -65,401,235 |
Now, we try dividing 65,401,235 by 3:
65,401,235 ÷ 3 = 21,800,411.6667
If the quotient is a whole number, then 3 and 21,800,411.6667 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 | 65,401,235 | |
| -1 | -65,401,235 |
Let's try dividing by 4:
65,401,235 ÷ 4 = 16,350,308.75
If the quotient is a whole number, then 4 and 16,350,308.75 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 | 65,401,235 | |
| -1 | 65,401,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 367 | 1,229 | 1,835 | 6,145 | 10,643 | 35,641 | 53,215 | 178,205 | 451,043 | 2,255,215 | 13,080,247 | 65,401,235 |
| -1 | -5 | -29 | -145 | -367 | -1,229 | -1,835 | -6,145 | -10,643 | -35,641 | -53,215 | -178,205 | -451,043 | -2,255,215 | -13,080,247 | -65,401,235 |
