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 614,636,477, 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 | 614,636,477 | |
| -1 | -614,636,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 614,636,477.
Example:
1 x 614,636,477 = 614,636,477
and
-1 x -614,636,477 = 614,636,477
Notice both answers equal 614,636,477
With that explanation out of the way, let's continue. Next, we take the number 614,636,477 and divide it by 2:
614,636,477 ÷ 2 = 307,318,238.5
If the quotient is a whole number, then 2 and 307,318,238.5 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 | 614,636,477 | |
| -1 | -614,636,477 |
Now, we try dividing 614,636,477 by 3:
614,636,477 ÷ 3 = 204,878,825.6667
If the quotient is a whole number, then 3 and 204,878,825.6667 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 | 614,636,477 | |
| -1 | -614,636,477 |
Let's try dividing by 4:
614,636,477 ÷ 4 = 153,659,119.25
If the quotient is a whole number, then 4 and 153,659,119.25 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 | 614,636,477 | |
| -1 | 614,636,477 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 2,441 | 2,767 | 17,087 | 19,369 | 31,733 | 35,971 | 222,131 | 251,797 | 6,754,247 | 47,279,729 | 87,805,211 | 614,636,477 |
| -1 | -7 | -13 | -91 | -2,441 | -2,767 | -17,087 | -19,369 | -31,733 | -35,971 | -222,131 | -251,797 | -6,754,247 | -47,279,729 | -87,805,211 | -614,636,477 |
