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 402,535, 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 | 402,535 | |
| -1 | -402,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 402,535.
Example:
1 x 402,535 = 402,535
and
-1 x -402,535 = 402,535
Notice both answers equal 402,535
With that explanation out of the way, let's continue. Next, we take the number 402,535 and divide it by 2:
402,535 ÷ 2 = 201,267.5
If the quotient is a whole number, then 2 and 201,267.5 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 | 402,535 | |
| -1 | -402,535 |
Now, we try dividing 402,535 by 3:
402,535 ÷ 3 = 134,178.3333
If the quotient is a whole number, then 3 and 134,178.3333 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 | 402,535 | |
| -1 | -402,535 |
Let's try dividing by 4:
402,535 ÷ 4 = 100,633.75
If the quotient is a whole number, then 4 and 100,633.75 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 | 402,535 | |
| -1 | 402,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 53 | 155 | 217 | 245 | 265 | 371 | 1,085 | 1,519 | 1,643 | 1,855 | 2,597 | 7,595 | 8,215 | 11,501 | 12,985 | 57,505 | 80,507 | 402,535 |
| -1 | -5 | -7 | -31 | -35 | -49 | -53 | -155 | -217 | -245 | -265 | -371 | -1,085 | -1,519 | -1,643 | -1,855 | -2,597 | -7,595 | -8,215 | -11,501 | -12,985 | -57,505 | -80,507 | -402,535 |
