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 267,155,063, 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 | 267,155,063 | |
| -1 | -267,155,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 267,155,063.
Example:
1 x 267,155,063 = 267,155,063
and
-1 x -267,155,063 = 267,155,063
Notice both answers equal 267,155,063
With that explanation out of the way, let's continue. Next, we take the number 267,155,063 and divide it by 2:
267,155,063 ÷ 2 = 133,577,531.5
If the quotient is a whole number, then 2 and 133,577,531.5 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 | 267,155,063 | |
| -1 | -267,155,063 |
Now, we try dividing 267,155,063 by 3:
267,155,063 ÷ 3 = 89,051,687.6667
If the quotient is a whole number, then 3 and 89,051,687.6667 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 | 267,155,063 | |
| -1 | -267,155,063 |
Let's try dividing by 4:
267,155,063 ÷ 4 = 66,788,765.75
If the quotient is a whole number, then 4 and 66,788,765.75 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 | 267,155,063 | |
| -1 | 267,155,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 149 | 469 | 1,043 | 3,823 | 9,983 | 26,761 | 69,881 | 256,141 | 569,627 | 1,792,987 | 3,987,389 | 38,165,009 | 267,155,063 |
| -1 | -7 | -67 | -149 | -469 | -1,043 | -3,823 | -9,983 | -26,761 | -69,881 | -256,141 | -569,627 | -1,792,987 | -3,987,389 | -38,165,009 | -267,155,063 |
