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 657,746,519, 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 | 657,746,519 | |
-1 | -657,746,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 657,746,519.
Example:
1 x 657,746,519 = 657,746,519
and
-1 x -657,746,519 = 657,746,519
Notice both answers equal 657,746,519
With that explanation out of the way, let's continue. Next, we take the number 657,746,519 and divide it by 2:
657,746,519 ÷ 2 = 328,873,259.5
If the quotient is a whole number, then 2 and 328,873,259.5 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 | 657,746,519 | |
-1 | -657,746,519 |
Now, we try dividing 657,746,519 by 3:
657,746,519 ÷ 3 = 219,248,839.6667
If the quotient is a whole number, then 3 and 219,248,839.6667 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 | 657,746,519 | |
-1 | -657,746,519 |
Let's try dividing by 4:
657,746,519 ÷ 4 = 164,436,629.75
If the quotient is a whole number, then 4 and 164,436,629.75 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 | 657,746,519 | |
-1 | 657,746,519 |
If you did it right, you will end up with this table:
1 | 173 | 3,802,003 | 657,746,519 |
-1 | -173 | -3,802,003 | -657,746,519 |
