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 266,122,531, 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 | 266,122,531 | |
| -1 | -266,122,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 266,122,531.
Example:
1 x 266,122,531 = 266,122,531
and
-1 x -266,122,531 = 266,122,531
Notice both answers equal 266,122,531
With that explanation out of the way, let's continue. Next, we take the number 266,122,531 and divide it by 2:
266,122,531 ÷ 2 = 133,061,265.5
If the quotient is a whole number, then 2 and 133,061,265.5 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 | 266,122,531 | |
| -1 | -266,122,531 |
Now, we try dividing 266,122,531 by 3:
266,122,531 ÷ 3 = 88,707,510.3333
If the quotient is a whole number, then 3 and 88,707,510.3333 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 | 266,122,531 | |
| -1 | -266,122,531 |
Let's try dividing by 4:
266,122,531 ÷ 4 = 66,530,632.75
If the quotient is a whole number, then 4 and 66,530,632.75 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 | 266,122,531 | |
| -1 | 266,122,531 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 127 | 551 | 2,413 | 3,683 | 3,803 | 69,977 | 72,257 | 110,287 | 482,981 | 2,095,453 | 9,176,639 | 14,006,449 | 266,122,531 |
| -1 | -19 | -29 | -127 | -551 | -2,413 | -3,683 | -3,803 | -69,977 | -72,257 | -110,287 | -482,981 | -2,095,453 | -9,176,639 | -14,006,449 | -266,122,531 |
