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 657,346,465, 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 | 657,346,465 | |
| -1 | -657,346,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 657,346,465.
Example:
1 x 657,346,465 = 657,346,465
and
-1 x -657,346,465 = 657,346,465
Notice both answers equal 657,346,465
With that explanation out of the way, let's continue. Next, we take the number 657,346,465 and divide it by 2:
657,346,465 ÷ 2 = 328,673,232.5
If the quotient is a whole number, then 2 and 328,673,232.5 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 | 657,346,465 | |
| -1 | -657,346,465 |
Now, we try dividing 657,346,465 by 3:
657,346,465 ÷ 3 = 219,115,488.3333
If the quotient is a whole number, then 3 and 219,115,488.3333 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 | 657,346,465 | |
| -1 | -657,346,465 |
Let's try dividing by 4:
657,346,465 ÷ 4 = 164,336,616.25
If the quotient is a whole number, then 4 and 164,336,616.25 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 | 657,346,465 | |
| -1 | 657,346,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 929 | 3,011 | 4,645 | 15,055 | 43,663 | 141,517 | 218,315 | 707,585 | 2,797,219 | 13,986,095 | 131,469,293 | 657,346,465 |
| -1 | -5 | -47 | -235 | -929 | -3,011 | -4,645 | -15,055 | -43,663 | -141,517 | -218,315 | -707,585 | -2,797,219 | -13,986,095 | -131,469,293 | -657,346,465 |
