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 165,516,151, 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 | 165,516,151 | |
-1 | -165,516,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 165,516,151.
Example:
1 x 165,516,151 = 165,516,151
and
-1 x -165,516,151 = 165,516,151
Notice both answers equal 165,516,151
With that explanation out of the way, let's continue. Next, we take the number 165,516,151 and divide it by 2:
165,516,151 ÷ 2 = 82,758,075.5
If the quotient is a whole number, then 2 and 82,758,075.5 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 | 165,516,151 | |
-1 | -165,516,151 |
Now, we try dividing 165,516,151 by 3:
165,516,151 ÷ 3 = 55,172,050.3333
If the quotient is a whole number, then 3 and 55,172,050.3333 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 | 165,516,151 | |
-1 | -165,516,151 |
Let's try dividing by 4:
165,516,151 ÷ 4 = 41,379,037.75
If the quotient is a whole number, then 4 and 41,379,037.75 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 | 165,516,151 | |
-1 | 165,516,151 |
If you did it right, you will end up with this table:
1 | 157 | 1,054,243 | 165,516,151 |
-1 | -157 | -1,054,243 | -165,516,151 |
