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 175,236,649, 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 | 175,236,649 | |
| -1 | -175,236,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 175,236,649.
Example:
1 x 175,236,649 = 175,236,649
and
-1 x -175,236,649 = 175,236,649
Notice both answers equal 175,236,649
With that explanation out of the way, let's continue. Next, we take the number 175,236,649 and divide it by 2:
175,236,649 ÷ 2 = 87,618,324.5
If the quotient is a whole number, then 2 and 87,618,324.5 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 | 175,236,649 | |
| -1 | -175,236,649 |
Now, we try dividing 175,236,649 by 3:
175,236,649 ÷ 3 = 58,412,216.3333
If the quotient is a whole number, then 3 and 58,412,216.3333 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 | 175,236,649 | |
| -1 | -175,236,649 |
Let's try dividing by 4:
175,236,649 ÷ 4 = 43,809,162.25
If the quotient is a whole number, then 4 and 43,809,162.25 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 | 175,236,649 | |
| -1 | 175,236,649 |
If you did it right, you will end up with this table:
| 1 | 7 | 157 | 317 | 503 | 1,099 | 2,219 | 3,521 | 49,769 | 78,971 | 159,451 | 348,383 | 552,797 | 1,116,157 | 25,033,807 | 175,236,649 |
| -1 | -7 | -157 | -317 | -503 | -1,099 | -2,219 | -3,521 | -49,769 | -78,971 | -159,451 | -348,383 | -552,797 | -1,116,157 | -25,033,807 | -175,236,649 |
