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 162,858,367, 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 | 162,858,367 | |
| -1 | -162,858,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,858,367.
Example:
1 x 162,858,367 = 162,858,367
and
-1 x -162,858,367 = 162,858,367
Notice both answers equal 162,858,367
With that explanation out of the way, let's continue. Next, we take the number 162,858,367 and divide it by 2:
162,858,367 ÷ 2 = 81,429,183.5
If the quotient is a whole number, then 2 and 81,429,183.5 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 | 162,858,367 | |
| -1 | -162,858,367 |
Now, we try dividing 162,858,367 by 3:
162,858,367 ÷ 3 = 54,286,122.3333
If the quotient is a whole number, then 3 and 54,286,122.3333 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 | 162,858,367 | |
| -1 | -162,858,367 |
Let's try dividing by 4:
162,858,367 ÷ 4 = 40,714,591.75
If the quotient is a whole number, then 4 and 40,714,591.75 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 | 162,858,367 | |
| -1 | 162,858,367 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 83 | 133 | 581 | 1,577 | 11,039 | 14,753 | 103,271 | 280,307 | 1,224,499 | 1,962,149 | 8,571,493 | 23,265,481 | 162,858,367 |
| -1 | -7 | -19 | -83 | -133 | -581 | -1,577 | -11,039 | -14,753 | -103,271 | -280,307 | -1,224,499 | -1,962,149 | -8,571,493 | -23,265,481 | -162,858,367 |
