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 266,662,529, 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 | 266,662,529 | |
| -1 | -266,662,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 266,662,529.
Example:
1 x 266,662,529 = 266,662,529
and
-1 x -266,662,529 = 266,662,529
Notice both answers equal 266,662,529
With that explanation out of the way, let's continue. Next, we take the number 266,662,529 and divide it by 2:
266,662,529 ÷ 2 = 133,331,264.5
If the quotient is a whole number, then 2 and 133,331,264.5 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 | 266,662,529 | |
| -1 | -266,662,529 |
Now, we try dividing 266,662,529 by 3:
266,662,529 ÷ 3 = 88,887,509.6667
If the quotient is a whole number, then 3 and 88,887,509.6667 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 | 266,662,529 | |
| -1 | -266,662,529 |
Let's try dividing by 4:
266,662,529 ÷ 4 = 66,665,632.25
If the quotient is a whole number, then 4 and 66,665,632.25 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 | 266,662,529 | |
| -1 | 266,662,529 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 1,151 | 1,439 | 8,057 | 10,073 | 26,473 | 33,097 | 185,311 | 231,679 | 1,656,289 | 11,594,023 | 38,094,647 | 266,662,529 |
| -1 | -7 | -23 | -161 | -1,151 | -1,439 | -8,057 | -10,073 | -26,473 | -33,097 | -185,311 | -231,679 | -1,656,289 | -11,594,023 | -38,094,647 | -266,662,529 |
