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 144,541,441, 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 | 144,541,441 | |
| -1 | -144,541,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,541,441.
Example:
1 x 144,541,441 = 144,541,441
and
-1 x -144,541,441 = 144,541,441
Notice both answers equal 144,541,441
With that explanation out of the way, let's continue. Next, we take the number 144,541,441 and divide it by 2:
144,541,441 ÷ 2 = 72,270,720.5
If the quotient is a whole number, then 2 and 72,270,720.5 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 | 144,541,441 | |
| -1 | -144,541,441 |
Now, we try dividing 144,541,441 by 3:
144,541,441 ÷ 3 = 48,180,480.3333
If the quotient is a whole number, then 3 and 48,180,480.3333 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 | 144,541,441 | |
| -1 | -144,541,441 |
Let's try dividing by 4:
144,541,441 ÷ 4 = 36,135,360.25
If the quotient is a whole number, then 4 and 36,135,360.25 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 | 144,541,441 | |
| -1 | 144,541,441 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 53 | 451 | 583 | 2,173 | 6,047 | 23,903 | 66,517 | 247,927 | 320,491 | 2,727,197 | 3,525,401 | 13,140,131 | 144,541,441 |
| -1 | -11 | -41 | -53 | -451 | -583 | -2,173 | -6,047 | -23,903 | -66,517 | -247,927 | -320,491 | -2,727,197 | -3,525,401 | -13,140,131 | -144,541,441 |
