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 144,500,455, 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 | 144,500,455 | |
| -1 | -144,500,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,500,455.
Example:
1 x 144,500,455 = 144,500,455
and
-1 x -144,500,455 = 144,500,455
Notice both answers equal 144,500,455
With that explanation out of the way, let's continue. Next, we take the number 144,500,455 and divide it by 2:
144,500,455 ÷ 2 = 72,250,227.5
If the quotient is a whole number, then 2 and 72,250,227.5 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 | 144,500,455 | |
| -1 | -144,500,455 |
Now, we try dividing 144,500,455 by 3:
144,500,455 ÷ 3 = 48,166,818.3333
If the quotient is a whole number, then 3 and 48,166,818.3333 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 | 144,500,455 | |
| -1 | -144,500,455 |
Let's try dividing by 4:
144,500,455 ÷ 4 = 36,125,113.75
If the quotient is a whole number, then 4 and 36,125,113.75 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 | 144,500,455 | |
| -1 | 144,500,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 84,751 | 423,755 | 932,261 | 2,627,281 | 4,661,305 | 13,136,405 | 28,900,091 | 144,500,455 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -84,751 | -423,755 | -932,261 | -2,627,281 | -4,661,305 | -13,136,405 | -28,900,091 | -144,500,455 |
