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 901,075, 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 | 901,075 | |
| -1 | -901,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 901,075.
Example:
1 x 901,075 = 901,075
and
-1 x -901,075 = 901,075
Notice both answers equal 901,075
With that explanation out of the way, let's continue. Next, we take the number 901,075 and divide it by 2:
901,075 ÷ 2 = 450,537.5
If the quotient is a whole number, then 2 and 450,537.5 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 | 901,075 | |
| -1 | -901,075 |
Now, we try dividing 901,075 by 3:
901,075 ÷ 3 = 300,358.3333
If the quotient is a whole number, then 3 and 300,358.3333 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 | 901,075 | |
| -1 | -901,075 |
Let's try dividing by 4:
901,075 ÷ 4 = 225,268.75
If the quotient is a whole number, then 4 and 225,268.75 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 | 901,075 | |
| -1 | 901,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 271 | 475 | 665 | 1,355 | 1,897 | 3,325 | 5,149 | 6,775 | 9,485 | 25,745 | 36,043 | 47,425 | 128,725 | 180,215 | 901,075 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -271 | -475 | -665 | -1,355 | -1,897 | -3,325 | -5,149 | -6,775 | -9,485 | -25,745 | -36,043 | -47,425 | -128,725 | -180,215 | -901,075 |
