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 165,026,533, 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 | 165,026,533 | |
| -1 | -165,026,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 165,026,533.
Example:
1 x 165,026,533 = 165,026,533
and
-1 x -165,026,533 = 165,026,533
Notice both answers equal 165,026,533
With that explanation out of the way, let's continue. Next, we take the number 165,026,533 and divide it by 2:
165,026,533 ÷ 2 = 82,513,266.5
If the quotient is a whole number, then 2 and 82,513,266.5 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 | 165,026,533 | |
| -1 | -165,026,533 |
Now, we try dividing 165,026,533 by 3:
165,026,533 ÷ 3 = 55,008,844.3333
If the quotient is a whole number, then 3 and 55,008,844.3333 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 | 165,026,533 | |
| -1 | -165,026,533 |
Let's try dividing by 4:
165,026,533 ÷ 4 = 41,256,633.25
If the quotient is a whole number, then 4 and 41,256,633.25 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 | 165,026,533 | |
| -1 | 165,026,533 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 61 | 133 | 427 | 1,159 | 8,113 | 20,341 | 142,387 | 386,479 | 1,240,801 | 2,705,353 | 8,685,607 | 23,575,219 | 165,026,533 |
| -1 | -7 | -19 | -61 | -133 | -427 | -1,159 | -8,113 | -20,341 | -142,387 | -386,479 | -1,240,801 | -2,705,353 | -8,685,607 | -23,575,219 | -165,026,533 |
