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 36,200,281, 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 | 36,200,281 | |
| -1 | -36,200,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,200,281.
Example:
1 x 36,200,281 = 36,200,281
and
-1 x -36,200,281 = 36,200,281
Notice both answers equal 36,200,281
With that explanation out of the way, let's continue. Next, we take the number 36,200,281 and divide it by 2:
36,200,281 ÷ 2 = 18,100,140.5
If the quotient is a whole number, then 2 and 18,100,140.5 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 | 36,200,281 | |
| -1 | -36,200,281 |
Now, we try dividing 36,200,281 by 3:
36,200,281 ÷ 3 = 12,066,760.3333
If the quotient is a whole number, then 3 and 12,066,760.3333 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 | 36,200,281 | |
| -1 | -36,200,281 |
Let's try dividing by 4:
36,200,281 ÷ 4 = 9,050,070.25
If the quotient is a whole number, then 4 and 9,050,070.25 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 | 36,200,281 | |
| -1 | 36,200,281 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 43 | 403 | 559 | 1,333 | 2,089 | 17,329 | 27,157 | 64,759 | 89,827 | 841,867 | 1,167,751 | 2,784,637 | 36,200,281 |
| -1 | -13 | -31 | -43 | -403 | -559 | -1,333 | -2,089 | -17,329 | -27,157 | -64,759 | -89,827 | -841,867 | -1,167,751 | -2,784,637 | -36,200,281 |
