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 267,015,151, 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 | 267,015,151 | |
| -1 | -267,015,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 267,015,151.
Example:
1 x 267,015,151 = 267,015,151
and
-1 x -267,015,151 = 267,015,151
Notice both answers equal 267,015,151
With that explanation out of the way, let's continue. Next, we take the number 267,015,151 and divide it by 2:
267,015,151 ÷ 2 = 133,507,575.5
If the quotient is a whole number, then 2 and 133,507,575.5 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 | 267,015,151 | |
| -1 | -267,015,151 |
Now, we try dividing 267,015,151 by 3:
267,015,151 ÷ 3 = 89,005,050.3333
If the quotient is a whole number, then 3 and 89,005,050.3333 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 | 267,015,151 | |
| -1 | -267,015,151 |
Let's try dividing by 4:
267,015,151 ÷ 4 = 66,753,787.75
If the quotient is a whole number, then 4 and 66,753,787.75 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 | 267,015,151 | |
| -1 | 267,015,151 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 29 | 247 | 377 | 551 | 7,163 | 37,277 | 484,601 | 708,263 | 1,081,033 | 9,207,419 | 14,053,429 | 20,539,627 | 267,015,151 |
| -1 | -13 | -19 | -29 | -247 | -377 | -551 | -7,163 | -37,277 | -484,601 | -708,263 | -1,081,033 | -9,207,419 | -14,053,429 | -20,539,627 | -267,015,151 |
