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 269,336,647, 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 | 269,336,647 | |
| -1 | -269,336,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 269,336,647.
Example:
1 x 269,336,647 = 269,336,647
and
-1 x -269,336,647 = 269,336,647
Notice both answers equal 269,336,647
With that explanation out of the way, let's continue. Next, we take the number 269,336,647 and divide it by 2:
269,336,647 ÷ 2 = 134,668,323.5
If the quotient is a whole number, then 2 and 134,668,323.5 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 | 269,336,647 | |
| -1 | -269,336,647 |
Now, we try dividing 269,336,647 by 3:
269,336,647 ÷ 3 = 89,778,882.3333
If the quotient is a whole number, then 3 and 89,778,882.3333 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 | 269,336,647 | |
| -1 | -269,336,647 |
Let's try dividing by 4:
269,336,647 ÷ 4 = 67,334,161.75
If the quotient is a whole number, then 4 and 67,334,161.75 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 | 269,336,647 | |
| -1 | 269,336,647 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 127 | 211 | 437 | 529 | 2,413 | 2,921 | 4,009 | 4,853 | 10,051 | 26,797 | 55,499 | 67,183 | 92,207 | 111,619 | 509,143 | 616,331 | 1,276,477 | 2,120,761 | 11,710,289 | 14,175,613 | 269,336,647 |
| -1 | -19 | -23 | -127 | -211 | -437 | -529 | -2,413 | -2,921 | -4,009 | -4,853 | -10,051 | -26,797 | -55,499 | -67,183 | -92,207 | -111,619 | -509,143 | -616,331 | -1,276,477 | -2,120,761 | -11,710,289 | -14,175,613 | -269,336,647 |
