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 177,620,737, 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 | 177,620,737 | |
| -1 | -177,620,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,620,737.
Example:
1 x 177,620,737 = 177,620,737
and
-1 x -177,620,737 = 177,620,737
Notice both answers equal 177,620,737
With that explanation out of the way, let's continue. Next, we take the number 177,620,737 and divide it by 2:
177,620,737 ÷ 2 = 88,810,368.5
If the quotient is a whole number, then 2 and 88,810,368.5 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 | 177,620,737 | |
| -1 | -177,620,737 |
Now, we try dividing 177,620,737 by 3:
177,620,737 ÷ 3 = 59,206,912.3333
If the quotient is a whole number, then 3 and 59,206,912.3333 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 | 177,620,737 | |
| -1 | -177,620,737 |
Let's try dividing by 4:
177,620,737 ÷ 4 = 44,405,184.25
If the quotient is a whole number, then 4 and 44,405,184.25 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 | 177,620,737 | |
| -1 | 177,620,737 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 203 | 239 | 523 | 1,421 | 1,673 | 3,661 | 6,931 | 11,711 | 15,167 | 25,627 | 48,517 | 106,169 | 124,997 | 339,619 | 743,183 | 874,979 | 3,624,913 | 6,124,853 | 25,374,391 | 177,620,737 |
| -1 | -7 | -29 | -49 | -203 | -239 | -523 | -1,421 | -1,673 | -3,661 | -6,931 | -11,711 | -15,167 | -25,627 | -48,517 | -106,169 | -124,997 | -339,619 | -743,183 | -874,979 | -3,624,913 | -6,124,853 | -25,374,391 | -177,620,737 |
