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 137,473,543, 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 | 137,473,543 | |
| -1 | -137,473,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,473,543.
Example:
1 x 137,473,543 = 137,473,543
and
-1 x -137,473,543 = 137,473,543
Notice both answers equal 137,473,543
With that explanation out of the way, let's continue. Next, we take the number 137,473,543 and divide it by 2:
137,473,543 ÷ 2 = 68,736,771.5
If the quotient is a whole number, then 2 and 68,736,771.5 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 | 137,473,543 | |
| -1 | -137,473,543 |
Now, we try dividing 137,473,543 by 3:
137,473,543 ÷ 3 = 45,824,514.3333
If the quotient is a whole number, then 3 and 45,824,514.3333 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 | 137,473,543 | |
| -1 | -137,473,543 |
Let's try dividing by 4:
137,473,543 ÷ 4 = 34,368,385.75
If the quotient is a whole number, then 4 and 34,368,385.75 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 | 137,473,543 | |
| -1 | 137,473,543 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 47 | 289 | 349 | 493 | 799 | 1,363 | 5,933 | 8,381 | 10,121 | 13,583 | 16,403 | 23,171 | 100,861 | 172,057 | 278,851 | 393,907 | 475,687 | 2,924,969 | 4,740,467 | 8,086,679 | 137,473,543 |
| -1 | -17 | -29 | -47 | -289 | -349 | -493 | -799 | -1,363 | -5,933 | -8,381 | -10,121 | -13,583 | -16,403 | -23,171 | -100,861 | -172,057 | -278,851 | -393,907 | -475,687 | -2,924,969 | -4,740,467 | -8,086,679 | -137,473,543 |
