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 237,765,281, 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 | 237,765,281 | |
| -1 | -237,765,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,765,281.
Example:
1 x 237,765,281 = 237,765,281
and
-1 x -237,765,281 = 237,765,281
Notice both answers equal 237,765,281
With that explanation out of the way, let's continue. Next, we take the number 237,765,281 and divide it by 2:
237,765,281 ÷ 2 = 118,882,640.5
If the quotient is a whole number, then 2 and 118,882,640.5 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 | 237,765,281 | |
| -1 | -237,765,281 |
Now, we try dividing 237,765,281 by 3:
237,765,281 ÷ 3 = 79,255,093.6667
If the quotient is a whole number, then 3 and 79,255,093.6667 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 | 237,765,281 | |
| -1 | -237,765,281 |
Let's try dividing by 4:
237,765,281 ÷ 4 = 59,441,320.25
If the quotient is a whole number, then 4 and 59,441,320.25 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 | 237,765,281 | |
| -1 | 237,765,281 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 137 | 221 | 1,781 | 2,329 | 7,853 | 30,277 | 102,089 | 133,501 | 1,075,861 | 1,735,513 | 13,986,193 | 18,289,637 | 237,765,281 |
| -1 | -13 | -17 | -137 | -221 | -1,781 | -2,329 | -7,853 | -30,277 | -102,089 | -133,501 | -1,075,861 | -1,735,513 | -13,986,193 | -18,289,637 | -237,765,281 |
