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 144,430,351, 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 | 144,430,351 | |
| -1 | -144,430,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,430,351.
Example:
1 x 144,430,351 = 144,430,351
and
-1 x -144,430,351 = 144,430,351
Notice both answers equal 144,430,351
With that explanation out of the way, let's continue. Next, we take the number 144,430,351 and divide it by 2:
144,430,351 ÷ 2 = 72,215,175.5
If the quotient is a whole number, then 2 and 72,215,175.5 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 | 144,430,351 | |
| -1 | -144,430,351 |
Now, we try dividing 144,430,351 by 3:
144,430,351 ÷ 3 = 48,143,450.3333
If the quotient is a whole number, then 3 and 48,143,450.3333 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 | 144,430,351 | |
| -1 | -144,430,351 |
Let's try dividing by 4:
144,430,351 ÷ 4 = 36,107,587.75
If the quotient is a whole number, then 4 and 36,107,587.75 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 | 144,430,351 | |
| -1 | 144,430,351 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 37 | 221 | 289 | 481 | 629 | 1,039 | 3,757 | 8,177 | 10,693 | 13,507 | 17,663 | 38,443 | 139,009 | 229,619 | 300,271 | 499,759 | 653,531 | 3,903,523 | 8,495,903 | 11,110,027 | 144,430,351 |
| -1 | -13 | -17 | -37 | -221 | -289 | -481 | -629 | -1,039 | -3,757 | -8,177 | -10,693 | -13,507 | -17,663 | -38,443 | -139,009 | -229,619 | -300,271 | -499,759 | -653,531 | -3,903,523 | -8,495,903 | -11,110,027 | -144,430,351 |
