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 237,818,573, 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 | 237,818,573 | |
| -1 | -237,818,573 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,818,573.
Example:
1 x 237,818,573 = 237,818,573
and
-1 x -237,818,573 = 237,818,573
Notice both answers equal 237,818,573
With that explanation out of the way, let's continue. Next, we take the number 237,818,573 and divide it by 2:
237,818,573 ÷ 2 = 118,909,286.5
If the quotient is a whole number, then 2 and 118,909,286.5 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 | 237,818,573 | |
| -1 | -237,818,573 |
Now, we try dividing 237,818,573 by 3:
237,818,573 ÷ 3 = 79,272,857.6667
If the quotient is a whole number, then 3 and 79,272,857.6667 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 | 237,818,573 | |
| -1 | -237,818,573 |
Let's try dividing by 4:
237,818,573 ÷ 4 = 59,454,643.25
If the quotient is a whole number, then 4 and 59,454,643.25 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 | 237,818,573 | |
| -1 | 237,818,573 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 41 | 223 | 703 | 779 | 1,369 | 1,517 | 4,237 | 8,251 | 9,143 | 26,011 | 28,823 | 56,129 | 156,769 | 173,717 | 305,287 | 338,291 | 1,066,451 | 5,800,453 | 6,427,529 | 12,516,767 | 237,818,573 |
| -1 | -19 | -37 | -41 | -223 | -703 | -779 | -1,369 | -1,517 | -4,237 | -8,251 | -9,143 | -26,011 | -28,823 | -56,129 | -156,769 | -173,717 | -305,287 | -338,291 | -1,066,451 | -5,800,453 | -6,427,529 | -12,516,767 | -237,818,573 |
