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 160,467,097, 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 | 160,467,097 | |
| -1 | -160,467,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,467,097.
Example:
1 x 160,467,097 = 160,467,097
and
-1 x -160,467,097 = 160,467,097
Notice both answers equal 160,467,097
With that explanation out of the way, let's continue. Next, we take the number 160,467,097 and divide it by 2:
160,467,097 ÷ 2 = 80,233,548.5
If the quotient is a whole number, then 2 and 80,233,548.5 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 | 160,467,097 | |
| -1 | -160,467,097 |
Now, we try dividing 160,467,097 by 3:
160,467,097 ÷ 3 = 53,489,032.3333
If the quotient is a whole number, then 3 and 53,489,032.3333 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 | 160,467,097 | |
| -1 | -160,467,097 |
Let's try dividing by 4:
160,467,097 ÷ 4 = 40,116,774.25
If the quotient is a whole number, then 4 and 40,116,774.25 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 | 160,467,097 | |
| -1 | 160,467,097 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 421 | 2,947 | 3,203 | 7,157 | 22,421 | 50,099 | 54,451 | 381,157 | 1,348,463 | 9,439,241 | 22,923,871 | 160,467,097 |
| -1 | -7 | -17 | -119 | -421 | -2,947 | -3,203 | -7,157 | -22,421 | -50,099 | -54,451 | -381,157 | -1,348,463 | -9,439,241 | -22,923,871 | -160,467,097 |
