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 177,371,051, 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 | 177,371,051 | |
| -1 | -177,371,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,371,051.
Example:
1 x 177,371,051 = 177,371,051
and
-1 x -177,371,051 = 177,371,051
Notice both answers equal 177,371,051
With that explanation out of the way, let's continue. Next, we take the number 177,371,051 and divide it by 2:
177,371,051 ÷ 2 = 88,685,525.5
If the quotient is a whole number, then 2 and 88,685,525.5 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 | 177,371,051 | |
| -1 | -177,371,051 |
Now, we try dividing 177,371,051 by 3:
177,371,051 ÷ 3 = 59,123,683.6667
If the quotient is a whole number, then 3 and 59,123,683.6667 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 | 177,371,051 | |
| -1 | -177,371,051 |
Let's try dividing by 4:
177,371,051 ÷ 4 = 44,342,762.75
If the quotient is a whole number, then 4 and 44,342,762.75 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 | 177,371,051 | |
| -1 | 177,371,051 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 59 | 143 | 649 | 767 | 8,437 | 21,023 | 231,253 | 273,299 | 1,240,357 | 3,006,289 | 13,643,927 | 16,124,641 | 177,371,051 |
| -1 | -11 | -13 | -59 | -143 | -649 | -767 | -8,437 | -21,023 | -231,253 | -273,299 | -1,240,357 | -3,006,289 | -13,643,927 | -16,124,641 | -177,371,051 |
