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 123,142,033, 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 | 123,142,033 | |
| -1 | -123,142,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,142,033.
Example:
1 x 123,142,033 = 123,142,033
and
-1 x -123,142,033 = 123,142,033
Notice both answers equal 123,142,033
With that explanation out of the way, let's continue. Next, we take the number 123,142,033 and divide it by 2:
123,142,033 ÷ 2 = 61,571,016.5
If the quotient is a whole number, then 2 and 61,571,016.5 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 | 123,142,033 | |
| -1 | -123,142,033 |
Now, we try dividing 123,142,033 by 3:
123,142,033 ÷ 3 = 41,047,344.3333
If the quotient is a whole number, then 3 and 41,047,344.3333 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 | 123,142,033 | |
| -1 | -123,142,033 |
Let's try dividing by 4:
123,142,033 ÷ 4 = 30,785,508.25
If the quotient is a whole number, then 4 and 30,785,508.25 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 | 123,142,033 | |
| -1 | 123,142,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 29 | 119 | 203 | 289 | 493 | 2,023 | 2,099 | 3,451 | 8,381 | 14,693 | 35,683 | 58,667 | 60,871 | 249,781 | 426,097 | 606,611 | 1,034,807 | 4,246,277 | 7,243,649 | 17,591,719 | 123,142,033 |
| -1 | -7 | -17 | -29 | -119 | -203 | -289 | -493 | -2,023 | -2,099 | -3,451 | -8,381 | -14,693 | -35,683 | -58,667 | -60,871 | -249,781 | -426,097 | -606,611 | -1,034,807 | -4,246,277 | -7,243,649 | -17,591,719 | -123,142,033 |
