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 123,737,497, 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 | 123,737,497 | |
| -1 | -123,737,497 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,737,497.
Example:
1 x 123,737,497 = 123,737,497
and
-1 x -123,737,497 = 123,737,497
Notice both answers equal 123,737,497
With that explanation out of the way, let's continue. Next, we take the number 123,737,497 and divide it by 2:
123,737,497 ÷ 2 = 61,868,748.5
If the quotient is a whole number, then 2 and 61,868,748.5 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 | 123,737,497 | |
| -1 | -123,737,497 |
Now, we try dividing 123,737,497 by 3:
123,737,497 ÷ 3 = 41,245,832.3333
If the quotient is a whole number, then 3 and 41,245,832.3333 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 | 123,737,497 | |
| -1 | -123,737,497 |
Let's try dividing by 4:
123,737,497 ÷ 4 = 30,934,374.25
If the quotient is a whole number, then 4 and 30,934,374.25 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 | 123,737,497 | |
| -1 | 123,737,497 |
If you did it right, you will end up with this table:
| 1 | 13 | 127 | 149 | 503 | 1,651 | 1,937 | 6,539 | 18,923 | 63,881 | 74,947 | 245,999 | 830,453 | 974,311 | 9,518,269 | 123,737,497 |
| -1 | -13 | -127 | -149 | -503 | -1,651 | -1,937 | -6,539 | -18,923 | -63,881 | -74,947 | -245,999 | -830,453 | -974,311 | -9,518,269 | -123,737,497 |
