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 614,222,465, 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 | 614,222,465 | |
| -1 | -614,222,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 614,222,465.
Example:
1 x 614,222,465 = 614,222,465
and
-1 x -614,222,465 = 614,222,465
Notice both answers equal 614,222,465
With that explanation out of the way, let's continue. Next, we take the number 614,222,465 and divide it by 2:
614,222,465 ÷ 2 = 307,111,232.5
If the quotient is a whole number, then 2 and 307,111,232.5 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 | 614,222,465 | |
| -1 | -614,222,465 |
Now, we try dividing 614,222,465 by 3:
614,222,465 ÷ 3 = 204,740,821.6667
If the quotient is a whole number, then 3 and 204,740,821.6667 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 | 614,222,465 | |
| -1 | -614,222,465 |
Let's try dividing by 4:
614,222,465 ÷ 4 = 153,555,616.25
If the quotient is a whole number, then 4 and 153,555,616.25 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 | 614,222,465 | |
| -1 | 614,222,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 157 | 785 | 4,553 | 22,765 | 26,981 | 134,905 | 782,449 | 3,912,245 | 4,236,017 | 21,180,085 | 122,844,493 | 614,222,465 |
| -1 | -5 | -29 | -145 | -157 | -785 | -4,553 | -22,765 | -26,981 | -134,905 | -782,449 | -3,912,245 | -4,236,017 | -21,180,085 | -122,844,493 | -614,222,465 |
