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 143,715,155, 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 | 143,715,155 | |
| -1 | -143,715,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,715,155.
Example:
1 x 143,715,155 = 143,715,155
and
-1 x -143,715,155 = 143,715,155
Notice both answers equal 143,715,155
With that explanation out of the way, let's continue. Next, we take the number 143,715,155 and divide it by 2:
143,715,155 ÷ 2 = 71,857,577.5
If the quotient is a whole number, then 2 and 71,857,577.5 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 | 143,715,155 | |
| -1 | -143,715,155 |
Now, we try dividing 143,715,155 by 3:
143,715,155 ÷ 3 = 47,905,051.6667
If the quotient is a whole number, then 3 and 47,905,051.6667 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 | 143,715,155 | |
| -1 | -143,715,155 |
Let's try dividing by 4:
143,715,155 ÷ 4 = 35,928,788.75
If the quotient is a whole number, then 4 and 35,928,788.75 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 | 143,715,155 | |
| -1 | 143,715,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 29 | 115 | 145 | 667 | 3,335 | 43,093 | 215,465 | 991,139 | 1,249,697 | 4,955,695 | 6,248,485 | 28,743,031 | 143,715,155 |
| -1 | -5 | -23 | -29 | -115 | -145 | -667 | -3,335 | -43,093 | -215,465 | -991,139 | -1,249,697 | -4,955,695 | -6,248,485 | -28,743,031 | -143,715,155 |
