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 237,481,675, 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 | 237,481,675 | |
| -1 | -237,481,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,481,675.
Example:
1 x 237,481,675 = 237,481,675
and
-1 x -237,481,675 = 237,481,675
Notice both answers equal 237,481,675
With that explanation out of the way, let's continue. Next, we take the number 237,481,675 and divide it by 2:
237,481,675 ÷ 2 = 118,740,837.5
If the quotient is a whole number, then 2 and 118,740,837.5 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 | 237,481,675 | |
| -1 | -237,481,675 |
Now, we try dividing 237,481,675 by 3:
237,481,675 ÷ 3 = 79,160,558.3333
If the quotient is a whole number, then 3 and 79,160,558.3333 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 | 237,481,675 | |
| -1 | -237,481,675 |
Let's try dividing by 4:
237,481,675 ÷ 4 = 59,370,418.75
If the quotient is a whole number, then 4 and 59,370,418.75 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 | 237,481,675 | |
| -1 | 237,481,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 83 | 193 | 415 | 593 | 965 | 2,075 | 2,965 | 4,825 | 14,825 | 16,019 | 49,219 | 80,095 | 114,449 | 246,095 | 400,475 | 572,245 | 1,230,475 | 2,861,225 | 9,499,267 | 47,496,335 | 237,481,675 |
| -1 | -5 | -25 | -83 | -193 | -415 | -593 | -965 | -2,075 | -2,965 | -4,825 | -14,825 | -16,019 | -49,219 | -80,095 | -114,449 | -246,095 | -400,475 | -572,245 | -1,230,475 | -2,861,225 | -9,499,267 | -47,496,335 | -237,481,675 |
