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 800,275, 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 | 800,275 | |
| -1 | -800,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 800,275.
Example:
1 x 800,275 = 800,275
and
-1 x -800,275 = 800,275
Notice both answers equal 800,275
With that explanation out of the way, let's continue. Next, we take the number 800,275 and divide it by 2:
800,275 ÷ 2 = 400,137.5
If the quotient is a whole number, then 2 and 400,137.5 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 | 800,275 | |
| -1 | -800,275 |
Now, we try dividing 800,275 by 3:
800,275 ÷ 3 = 266,758.3333
If the quotient is a whole number, then 3 and 266,758.3333 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 | 800,275 | |
| -1 | -800,275 |
Let's try dividing by 4:
800,275 ÷ 4 = 200,068.75
If the quotient is a whole number, then 4 and 200,068.75 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 | 800,275 | |
| -1 | 800,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 85 | 119 | 175 | 269 | 425 | 595 | 1,345 | 1,883 | 2,975 | 4,573 | 6,725 | 9,415 | 22,865 | 32,011 | 47,075 | 114,325 | 160,055 | 800,275 |
| -1 | -5 | -7 | -17 | -25 | -35 | -85 | -119 | -175 | -269 | -425 | -595 | -1,345 | -1,883 | -2,975 | -4,573 | -6,725 | -9,415 | -22,865 | -32,011 | -47,075 | -114,325 | -160,055 | -800,275 |
