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 19,167,775, 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 | 19,167,775 | |
| -1 | -19,167,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,167,775.
Example:
1 x 19,167,775 = 19,167,775
and
-1 x -19,167,775 = 19,167,775
Notice both answers equal 19,167,775
With that explanation out of the way, let's continue. Next, we take the number 19,167,775 and divide it by 2:
19,167,775 ÷ 2 = 9,583,887.5
If the quotient is a whole number, then 2 and 9,583,887.5 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 | 19,167,775 | |
| -1 | -19,167,775 |
Now, we try dividing 19,167,775 by 3:
19,167,775 ÷ 3 = 6,389,258.3333
If the quotient is a whole number, then 3 and 6,389,258.3333 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 | 19,167,775 | |
| -1 | -19,167,775 |
Let's try dividing by 4:
19,167,775 ÷ 4 = 4,791,943.75
If the quotient is a whole number, then 4 and 4,791,943.75 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 | 19,167,775 | |
| -1 | 19,167,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 47 | 55 | 235 | 275 | 517 | 1,175 | 1,483 | 2,585 | 7,415 | 12,925 | 16,313 | 37,075 | 69,701 | 81,565 | 348,505 | 407,825 | 766,711 | 1,742,525 | 3,833,555 | 19,167,775 |
| -1 | -5 | -11 | -25 | -47 | -55 | -235 | -275 | -517 | -1,175 | -1,483 | -2,585 | -7,415 | -12,925 | -16,313 | -37,075 | -69,701 | -81,565 | -348,505 | -407,825 | -766,711 | -1,742,525 | -3,833,555 | -19,167,775 |
