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 137,467,627, 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 | 137,467,627 | |
| -1 | -137,467,627 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,467,627.
Example:
1 x 137,467,627 = 137,467,627
and
-1 x -137,467,627 = 137,467,627
Notice both answers equal 137,467,627
With that explanation out of the way, let's continue. Next, we take the number 137,467,627 and divide it by 2:
137,467,627 ÷ 2 = 68,733,813.5
If the quotient is a whole number, then 2 and 68,733,813.5 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 | 137,467,627 | |
| -1 | -137,467,627 |
Now, we try dividing 137,467,627 by 3:
137,467,627 ÷ 3 = 45,822,542.3333
If the quotient is a whole number, then 3 and 45,822,542.3333 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 | 137,467,627 | |
| -1 | -137,467,627 |
Let's try dividing by 4:
137,467,627 ÷ 4 = 34,366,906.75
If the quotient is a whole number, then 4 and 34,366,906.75 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 | 137,467,627 | |
| -1 | 137,467,627 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 29 | 187 | 319 | 493 | 5,423 | 25,349 | 278,839 | 430,933 | 735,121 | 4,740,263 | 8,086,331 | 12,497,057 | 137,467,627 |
| -1 | -11 | -17 | -29 | -187 | -319 | -493 | -5,423 | -25,349 | -278,839 | -430,933 | -735,121 | -4,740,263 | -8,086,331 | -12,497,057 | -137,467,627 |
