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 177,371,537, 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 | 177,371,537 | |
| -1 | -177,371,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,371,537.
Example:
1 x 177,371,537 = 177,371,537
and
-1 x -177,371,537 = 177,371,537
Notice both answers equal 177,371,537
With that explanation out of the way, let's continue. Next, we take the number 177,371,537 and divide it by 2:
177,371,537 ÷ 2 = 88,685,768.5
If the quotient is a whole number, then 2 and 88,685,768.5 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 | 177,371,537 | |
| -1 | -177,371,537 |
Now, we try dividing 177,371,537 by 3:
177,371,537 ÷ 3 = 59,123,845.6667
If the quotient is a whole number, then 3 and 59,123,845.6667 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 | 177,371,537 | |
| -1 | -177,371,537 |
Let's try dividing by 4:
177,371,537 ÷ 4 = 44,342,884.25
If the quotient is a whole number, then 4 and 44,342,884.25 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 | 177,371,537 | |
| -1 | 177,371,537 |
If you did it right, you will end up with this table:
| 1 | 7 | 149 | 173 | 983 | 1,043 | 1,211 | 6,881 | 25,777 | 146,467 | 170,059 | 180,439 | 1,025,269 | 1,190,413 | 25,338,791 | 177,371,537 |
| -1 | -7 | -149 | -173 | -983 | -1,043 | -1,211 | -6,881 | -25,777 | -146,467 | -170,059 | -180,439 | -1,025,269 | -1,190,413 | -25,338,791 | -177,371,537 |
