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 16,773,475, 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 | 16,773,475 | |
| -1 | -16,773,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,773,475.
Example:
1 x 16,773,475 = 16,773,475
and
-1 x -16,773,475 = 16,773,475
Notice both answers equal 16,773,475
With that explanation out of the way, let's continue. Next, we take the number 16,773,475 and divide it by 2:
16,773,475 ÷ 2 = 8,386,737.5
If the quotient is a whole number, then 2 and 8,386,737.5 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 | 16,773,475 | |
| -1 | -16,773,475 |
Now, we try dividing 16,773,475 by 3:
16,773,475 ÷ 3 = 5,591,158.3333
If the quotient is a whole number, then 3 and 5,591,158.3333 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 | 16,773,475 | |
| -1 | -16,773,475 |
Let's try dividing by 4:
16,773,475 ÷ 4 = 4,193,368.75
If the quotient is a whole number, then 4 and 4,193,368.75 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 | 16,773,475 | |
| -1 | 16,773,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 61 | 85 | 305 | 425 | 647 | 1,037 | 1,525 | 3,235 | 5,185 | 10,999 | 16,175 | 25,925 | 39,467 | 54,995 | 197,335 | 274,975 | 670,939 | 986,675 | 3,354,695 | 16,773,475 |
| -1 | -5 | -17 | -25 | -61 | -85 | -305 | -425 | -647 | -1,037 | -1,525 | -3,235 | -5,185 | -10,999 | -16,175 | -25,925 | -39,467 | -54,995 | -197,335 | -274,975 | -670,939 | -986,675 | -3,354,695 | -16,773,475 |
