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 261,456,629, 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 | 261,456,629 | |
| -1 | -261,456,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 261,456,629.
Example:
1 x 261,456,629 = 261,456,629
and
-1 x -261,456,629 = 261,456,629
Notice both answers equal 261,456,629
With that explanation out of the way, let's continue. Next, we take the number 261,456,629 and divide it by 2:
261,456,629 ÷ 2 = 130,728,314.5
If the quotient is a whole number, then 2 and 130,728,314.5 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 | 261,456,629 | |
| -1 | -261,456,629 |
Now, we try dividing 261,456,629 by 3:
261,456,629 ÷ 3 = 87,152,209.6667
If the quotient is a whole number, then 3 and 87,152,209.6667 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 | 261,456,629 | |
| -1 | -261,456,629 |
Let's try dividing by 4:
261,456,629 ÷ 4 = 65,364,157.25
If the quotient is a whole number, then 4 and 65,364,157.25 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 | 261,456,629 | |
| -1 | 261,456,629 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 329 | 653 | 1,217 | 4,571 | 8,519 | 30,691 | 57,199 | 214,837 | 400,393 | 794,701 | 5,562,907 | 37,350,947 | 261,456,629 |
| -1 | -7 | -47 | -329 | -653 | -1,217 | -4,571 | -8,519 | -30,691 | -57,199 | -214,837 | -400,393 | -794,701 | -5,562,907 | -37,350,947 | -261,456,629 |
