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 746,866,801, 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 | 746,866,801 | |
| -1 | -746,866,801 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 746,866,801.
Example:
1 x 746,866,801 = 746,866,801
and
-1 x -746,866,801 = 746,866,801
Notice both answers equal 746,866,801
With that explanation out of the way, let's continue. Next, we take the number 746,866,801 and divide it by 2:
746,866,801 ÷ 2 = 373,433,400.5
If the quotient is a whole number, then 2 and 373,433,400.5 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 | 746,866,801 | |
| -1 | -746,866,801 |
Now, we try dividing 746,866,801 by 3:
746,866,801 ÷ 3 = 248,955,600.3333
If the quotient is a whole number, then 3 and 248,955,600.3333 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 | 746,866,801 | |
| -1 | -746,866,801 |
Let's try dividing by 4:
746,866,801 ÷ 4 = 186,716,700.25
If the quotient is a whole number, then 4 and 186,716,700.25 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 | 746,866,801 | |
| -1 | 746,866,801 |
If you did it right, you will end up with this table:
| 1 | 19 | 47 | 109 | 893 | 2,071 | 5,123 | 7,673 | 97,337 | 145,787 | 360,631 | 836,357 | 6,851,989 | 15,890,783 | 39,308,779 | 746,866,801 |
| -1 | -19 | -47 | -109 | -893 | -2,071 | -5,123 | -7,673 | -97,337 | -145,787 | -360,631 | -836,357 | -6,851,989 | -15,890,783 | -39,308,779 | -746,866,801 |
