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 152,075, 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 | 152,075 | |
| -1 | -152,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,075.
Example:
1 x 152,075 = 152,075
and
-1 x -152,075 = 152,075
Notice both answers equal 152,075
With that explanation out of the way, let's continue. Next, we take the number 152,075 and divide it by 2:
152,075 ÷ 2 = 76,037.5
If the quotient is a whole number, then 2 and 76,037.5 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 | 152,075 | |
| -1 | -152,075 |
Now, we try dividing 152,075 by 3:
152,075 ÷ 3 = 50,691.6667
If the quotient is a whole number, then 3 and 50,691.6667 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 | 152,075 | |
| -1 | -152,075 |
Let's try dividing by 4:
152,075 ÷ 4 = 38,018.75
If the quotient is a whole number, then 4 and 38,018.75 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 | 152,075 | |
| -1 | 152,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 79 | 175 | 275 | 385 | 395 | 553 | 869 | 1,925 | 1,975 | 2,765 | 4,345 | 6,083 | 13,825 | 21,725 | 30,415 | 152,075 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -79 | -175 | -275 | -385 | -395 | -553 | -869 | -1,925 | -1,975 | -2,765 | -4,345 | -6,083 | -13,825 | -21,725 | -30,415 | -152,075 |
