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 19,000,075, 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 | 19,000,075 | |
| -1 | -19,000,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,000,075.
Example:
1 x 19,000,075 = 19,000,075
and
-1 x -19,000,075 = 19,000,075
Notice both answers equal 19,000,075
With that explanation out of the way, let's continue. Next, we take the number 19,000,075 and divide it by 2:
19,000,075 ÷ 2 = 9,500,037.5
If the quotient is a whole number, then 2 and 9,500,037.5 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 | 19,000,075 | |
| -1 | -19,000,075 |
Now, we try dividing 19,000,075 by 3:
19,000,075 ÷ 3 = 6,333,358.3333
If the quotient is a whole number, then 3 and 6,333,358.3333 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 | 19,000,075 | |
| -1 | -19,000,075 |
Let's try dividing by 4:
19,000,075 ÷ 4 = 4,750,018.75
If the quotient is a whole number, then 4 and 4,750,018.75 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 | 19,000,075 | |
| -1 | 19,000,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 73 | 145 | 359 | 365 | 725 | 1,795 | 1,825 | 2,117 | 8,975 | 10,411 | 10,585 | 26,207 | 52,055 | 52,925 | 131,035 | 260,275 | 655,175 | 760,003 | 3,800,015 | 19,000,075 |
| -1 | -5 | -25 | -29 | -73 | -145 | -359 | -365 | -725 | -1,795 | -1,825 | -2,117 | -8,975 | -10,411 | -10,585 | -26,207 | -52,055 | -52,925 | -131,035 | -260,275 | -655,175 | -760,003 | -3,800,015 | -19,000,075 |
