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 266,320,543, 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 | 266,320,543 | |
| -1 | -266,320,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 266,320,543.
Example:
1 x 266,320,543 = 266,320,543
and
-1 x -266,320,543 = 266,320,543
Notice both answers equal 266,320,543
With that explanation out of the way, let's continue. Next, we take the number 266,320,543 and divide it by 2:
266,320,543 ÷ 2 = 133,160,271.5
If the quotient is a whole number, then 2 and 133,160,271.5 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 | 266,320,543 | |
| -1 | -266,320,543 |
Now, we try dividing 266,320,543 by 3:
266,320,543 ÷ 3 = 88,773,514.3333
If the quotient is a whole number, then 3 and 88,773,514.3333 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 | 266,320,543 | |
| -1 | -266,320,543 |
Let's try dividing by 4:
266,320,543 ÷ 4 = 66,580,135.75
If the quotient is a whole number, then 4 and 66,580,135.75 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 | 266,320,543 | |
| -1 | 266,320,543 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 43 | 1,189 | 1,247 | 1,763 | 5,209 | 51,127 | 151,061 | 213,569 | 223,987 | 6,193,501 | 6,495,623 | 9,183,467 | 266,320,543 |
| -1 | -29 | -41 | -43 | -1,189 | -1,247 | -1,763 | -5,209 | -51,127 | -151,061 | -213,569 | -223,987 | -6,193,501 | -6,495,623 | -9,183,467 | -266,320,543 |
