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 175,694,197, 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 | 175,694,197 | |
| -1 | -175,694,197 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 175,694,197.
Example:
1 x 175,694,197 = 175,694,197
and
-1 x -175,694,197 = 175,694,197
Notice both answers equal 175,694,197
With that explanation out of the way, let's continue. Next, we take the number 175,694,197 and divide it by 2:
175,694,197 ÷ 2 = 87,847,098.5
If the quotient is a whole number, then 2 and 87,847,098.5 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 | 175,694,197 | |
| -1 | -175,694,197 |
Now, we try dividing 175,694,197 by 3:
175,694,197 ÷ 3 = 58,564,732.3333
If the quotient is a whole number, then 3 and 58,564,732.3333 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 | 175,694,197 | |
| -1 | -175,694,197 |
Let's try dividing by 4:
175,694,197 ÷ 4 = 43,923,549.25
If the quotient is a whole number, then 4 and 43,923,549.25 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 | 175,694,197 | |
| -1 | 175,694,197 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 751 | 1,759 | 5,257 | 12,313 | 14,269 | 33,421 | 99,883 | 233,947 | 1,321,009 | 9,247,063 | 25,099,171 | 175,694,197 |
| -1 | -7 | -19 | -133 | -751 | -1,759 | -5,257 | -12,313 | -14,269 | -33,421 | -99,883 | -233,947 | -1,321,009 | -9,247,063 | -25,099,171 | -175,694,197 |
