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 144,133,415, 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 | 144,133,415 | |
| -1 | -144,133,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,133,415.
Example:
1 x 144,133,415 = 144,133,415
and
-1 x -144,133,415 = 144,133,415
Notice both answers equal 144,133,415
With that explanation out of the way, let's continue. Next, we take the number 144,133,415 and divide it by 2:
144,133,415 ÷ 2 = 72,066,707.5
If the quotient is a whole number, then 2 and 72,066,707.5 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 | 144,133,415 | |
| -1 | -144,133,415 |
Now, we try dividing 144,133,415 by 3:
144,133,415 ÷ 3 = 48,044,471.6667
If the quotient is a whole number, then 3 and 48,044,471.6667 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 | 144,133,415 | |
| -1 | -144,133,415 |
Let's try dividing by 4:
144,133,415 ÷ 4 = 36,033,353.75
If the quotient is a whole number, then 4 and 36,033,353.75 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 | 144,133,415 | |
| -1 | 144,133,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 67 | 155 | 335 | 2,077 | 10,385 | 13,879 | 69,395 | 430,249 | 929,893 | 2,151,245 | 4,649,465 | 28,826,683 | 144,133,415 |
| -1 | -5 | -31 | -67 | -155 | -335 | -2,077 | -10,385 | -13,879 | -69,395 | -430,249 | -929,893 | -2,151,245 | -4,649,465 | -28,826,683 | -144,133,415 |
