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 65,116,151, 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 | 65,116,151 | |
| -1 | -65,116,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,116,151.
Example:
1 x 65,116,151 = 65,116,151
and
-1 x -65,116,151 = 65,116,151
Notice both answers equal 65,116,151
With that explanation out of the way, let's continue. Next, we take the number 65,116,151 and divide it by 2:
65,116,151 ÷ 2 = 32,558,075.5
If the quotient is a whole number, then 2 and 32,558,075.5 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 | 65,116,151 | |
| -1 | -65,116,151 |
Now, we try dividing 65,116,151 by 3:
65,116,151 ÷ 3 = 21,705,383.6667
If the quotient is a whole number, then 3 and 21,705,383.6667 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 | 65,116,151 | |
| -1 | -65,116,151 |
Let's try dividing by 4:
65,116,151 ÷ 4 = 16,279,037.75
If the quotient is a whole number, then 4 and 16,279,037.75 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 | 65,116,151 | |
| -1 | 65,116,151 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 271 | 337 | 713 | 6,233 | 7,751 | 8,401 | 10,447 | 91,327 | 193,223 | 240,281 | 2,100,521 | 2,831,137 | 65,116,151 |
| -1 | -23 | -31 | -271 | -337 | -713 | -6,233 | -7,751 | -8,401 | -10,447 | -91,327 | -193,223 | -240,281 | -2,100,521 | -2,831,137 | -65,116,151 |
