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 144,220,367, 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 | 144,220,367 | |
| -1 | -144,220,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,220,367.
Example:
1 x 144,220,367 = 144,220,367
and
-1 x -144,220,367 = 144,220,367
Notice both answers equal 144,220,367
With that explanation out of the way, let's continue. Next, we take the number 144,220,367 and divide it by 2:
144,220,367 ÷ 2 = 72,110,183.5
If the quotient is a whole number, then 2 and 72,110,183.5 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 | 144,220,367 | |
| -1 | -144,220,367 |
Now, we try dividing 144,220,367 by 3:
144,220,367 ÷ 3 = 48,073,455.6667
If the quotient is a whole number, then 3 and 48,073,455.6667 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 | 144,220,367 | |
| -1 | -144,220,367 |
Let's try dividing by 4:
144,220,367 ÷ 4 = 36,055,091.75
If the quotient is a whole number, then 4 and 36,055,091.75 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 | 144,220,367 | |
| -1 | 144,220,367 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 59 | 901 | 1,003 | 2,713 | 3,127 | 46,121 | 53,159 | 143,789 | 160,067 | 2,444,413 | 2,721,139 | 8,483,551 | 144,220,367 |
| -1 | -17 | -53 | -59 | -901 | -1,003 | -2,713 | -3,127 | -46,121 | -53,159 | -143,789 | -160,067 | -2,444,413 | -2,721,139 | -8,483,551 | -144,220,367 |
