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 144,051,215, 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 | 144,051,215 | |
| -1 | -144,051,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,051,215.
Example:
1 x 144,051,215 = 144,051,215
and
-1 x -144,051,215 = 144,051,215
Notice both answers equal 144,051,215
With that explanation out of the way, let's continue. Next, we take the number 144,051,215 and divide it by 2:
144,051,215 ÷ 2 = 72,025,607.5
If the quotient is a whole number, then 2 and 72,025,607.5 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 | 144,051,215 | |
| -1 | -144,051,215 |
Now, we try dividing 144,051,215 by 3:
144,051,215 ÷ 3 = 48,017,071.6667
If the quotient is a whole number, then 3 and 48,017,071.6667 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 | 144,051,215 | |
| -1 | -144,051,215 |
Let's try dividing by 4:
144,051,215 ÷ 4 = 36,012,803.75
If the quotient is a whole number, then 4 and 36,012,803.75 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 | 144,051,215 | |
| -1 | 144,051,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 374,159 | 1,870,795 | 2,619,113 | 4,115,749 | 13,095,565 | 20,578,745 | 28,810,243 | 144,051,215 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -374,159 | -1,870,795 | -2,619,113 | -4,115,749 | -13,095,565 | -20,578,745 | -28,810,243 | -144,051,215 |
