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 144,210,011, 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 | 144,210,011 | |
| -1 | -144,210,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,210,011.
Example:
1 x 144,210,011 = 144,210,011
and
-1 x -144,210,011 = 144,210,011
Notice both answers equal 144,210,011
With that explanation out of the way, let's continue. Next, we take the number 144,210,011 and divide it by 2:
144,210,011 ÷ 2 = 72,105,005.5
If the quotient is a whole number, then 2 and 72,105,005.5 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 | 144,210,011 | |
| -1 | -144,210,011 |
Now, we try dividing 144,210,011 by 3:
144,210,011 ÷ 3 = 48,070,003.6667
If the quotient is a whole number, then 3 and 48,070,003.6667 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 | 144,210,011 | |
| -1 | -144,210,011 |
Let's try dividing by 4:
144,210,011 ÷ 4 = 36,052,502.75
If the quotient is a whole number, then 4 and 36,052,502.75 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 | 144,210,011 | |
| -1 | 144,210,011 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 167 | 319 | 1,837 | 2,707 | 4,843 | 29,777 | 53,273 | 78,503 | 452,069 | 863,533 | 4,972,759 | 13,110,001 | 144,210,011 |
| -1 | -11 | -29 | -167 | -319 | -1,837 | -2,707 | -4,843 | -29,777 | -53,273 | -78,503 | -452,069 | -863,533 | -4,972,759 | -13,110,001 | -144,210,011 |
