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 144,143,455, 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 | 144,143,455 | |
| -1 | -144,143,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,143,455.
Example:
1 x 144,143,455 = 144,143,455
and
-1 x -144,143,455 = 144,143,455
Notice both answers equal 144,143,455
With that explanation out of the way, let's continue. Next, we take the number 144,143,455 and divide it by 2:
144,143,455 ÷ 2 = 72,071,727.5
If the quotient is a whole number, then 2 and 72,071,727.5 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 | 144,143,455 | |
| -1 | -144,143,455 |
Now, we try dividing 144,143,455 by 3:
144,143,455 ÷ 3 = 48,047,818.3333
If the quotient is a whole number, then 3 and 48,047,818.3333 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 | 144,143,455 | |
| -1 | -144,143,455 |
Let's try dividing by 4:
144,143,455 ÷ 4 = 36,035,863.75
If the quotient is a whole number, then 4 and 36,035,863.75 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 | 144,143,455 | |
| -1 | 144,143,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 439 | 485 | 677 | 2,195 | 3,385 | 42,583 | 65,669 | 212,915 | 297,203 | 328,345 | 1,486,015 | 28,828,691 | 144,143,455 |
| -1 | -5 | -97 | -439 | -485 | -677 | -2,195 | -3,385 | -42,583 | -65,669 | -212,915 | -297,203 | -328,345 | -1,486,015 | -28,828,691 | -144,143,455 |
