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 144,756,475, 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 | 144,756,475 | |
| -1 | -144,756,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,756,475.
Example:
1 x 144,756,475 = 144,756,475
and
-1 x -144,756,475 = 144,756,475
Notice both answers equal 144,756,475
With that explanation out of the way, let's continue. Next, we take the number 144,756,475 and divide it by 2:
144,756,475 ÷ 2 = 72,378,237.5
If the quotient is a whole number, then 2 and 72,378,237.5 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 | 144,756,475 | |
| -1 | -144,756,475 |
Now, we try dividing 144,756,475 by 3:
144,756,475 ÷ 3 = 48,252,158.3333
If the quotient is a whole number, then 3 and 48,252,158.3333 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 | 144,756,475 | |
| -1 | -144,756,475 |
Let's try dividing by 4:
144,756,475 ÷ 4 = 36,189,118.75
If the quotient is a whole number, then 4 and 36,189,118.75 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 | 144,756,475 | |
| -1 | 144,756,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 235 | 349 | 353 | 1,175 | 1,745 | 1,765 | 8,725 | 8,825 | 16,403 | 16,591 | 82,015 | 82,955 | 123,197 | 410,075 | 414,775 | 615,985 | 3,079,925 | 5,790,259 | 28,951,295 | 144,756,475 |
| -1 | -5 | -25 | -47 | -235 | -349 | -353 | -1,175 | -1,745 | -1,765 | -8,725 | -8,825 | -16,403 | -16,591 | -82,015 | -82,955 | -123,197 | -410,075 | -414,775 | -615,985 | -3,079,925 | -5,790,259 | -28,951,295 | -144,756,475 |
