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 10,176,551, 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 | 10,176,551 | |
| -1 | -10,176,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,176,551.
Example:
1 x 10,176,551 = 10,176,551
and
-1 x -10,176,551 = 10,176,551
Notice both answers equal 10,176,551
With that explanation out of the way, let's continue. Next, we take the number 10,176,551 and divide it by 2:
10,176,551 ÷ 2 = 5,088,275.5
If the quotient is a whole number, then 2 and 5,088,275.5 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 | 10,176,551 | |
| -1 | -10,176,551 |
Now, we try dividing 10,176,551 by 3:
10,176,551 ÷ 3 = 3,392,183.6667
If the quotient is a whole number, then 3 and 3,392,183.6667 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 | 10,176,551 | |
| -1 | -10,176,551 |
Let's try dividing by 4:
10,176,551 ÷ 4 = 2,544,137.75
If the quotient is a whole number, then 4 and 2,544,137.75 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 | 10,176,551 | |
| -1 | 10,176,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 149 | 887 | 1,043 | 1,639 | 6,209 | 9,757 | 11,473 | 68,299 | 132,163 | 925,141 | 1,453,793 | 10,176,551 |
| -1 | -7 | -11 | -77 | -149 | -887 | -1,043 | -1,639 | -6,209 | -9,757 | -11,473 | -68,299 | -132,163 | -925,141 | -1,453,793 | -10,176,551 |
