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 179,076,305, 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 | 179,076,305 | |
| -1 | -179,076,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 179,076,305.
Example:
1 x 179,076,305 = 179,076,305
and
-1 x -179,076,305 = 179,076,305
Notice both answers equal 179,076,305
With that explanation out of the way, let's continue. Next, we take the number 179,076,305 and divide it by 2:
179,076,305 ÷ 2 = 89,538,152.5
If the quotient is a whole number, then 2 and 89,538,152.5 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 | 179,076,305 | |
| -1 | -179,076,305 |
Now, we try dividing 179,076,305 by 3:
179,076,305 ÷ 3 = 59,692,101.6667
If the quotient is a whole number, then 3 and 59,692,101.6667 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 | 179,076,305 | |
| -1 | -179,076,305 |
Let's try dividing by 4:
179,076,305 ÷ 4 = 44,769,076.25
If the quotient is a whole number, then 4 and 44,769,076.25 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 | 179,076,305 | |
| -1 | 179,076,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 145 | 155 | 899 | 4,495 | 39,839 | 199,195 | 1,155,331 | 1,235,009 | 5,776,655 | 6,175,045 | 35,815,261 | 179,076,305 |
| -1 | -5 | -29 | -31 | -145 | -155 | -899 | -4,495 | -39,839 | -199,195 | -1,155,331 | -1,235,009 | -5,776,655 | -6,175,045 | -35,815,261 | -179,076,305 |
