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 143,424,103, 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 | 143,424,103 | |
| -1 | -143,424,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,424,103.
Example:
1 x 143,424,103 = 143,424,103
and
-1 x -143,424,103 = 143,424,103
Notice both answers equal 143,424,103
With that explanation out of the way, let's continue. Next, we take the number 143,424,103 and divide it by 2:
143,424,103 ÷ 2 = 71,712,051.5
If the quotient is a whole number, then 2 and 71,712,051.5 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 | 143,424,103 | |
| -1 | -143,424,103 |
Now, we try dividing 143,424,103 by 3:
143,424,103 ÷ 3 = 47,808,034.3333
If the quotient is a whole number, then 3 and 47,808,034.3333 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 | 143,424,103 | |
| -1 | -143,424,103 |
Let's try dividing by 4:
143,424,103 ÷ 4 = 35,856,025.75
If the quotient is a whole number, then 4 and 35,856,025.75 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 | 143,424,103 | |
| -1 | 143,424,103 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 97 | 1,121 | 1,319 | 1,843 | 5,723 | 25,061 | 77,821 | 108,737 | 127,943 | 1,478,599 | 2,430,917 | 7,548,637 | 143,424,103 |
| -1 | -19 | -59 | -97 | -1,121 | -1,319 | -1,843 | -5,723 | -25,061 | -77,821 | -108,737 | -127,943 | -1,478,599 | -2,430,917 | -7,548,637 | -143,424,103 |
