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 143,613,569, 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 | 143,613,569 | |
| -1 | -143,613,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,613,569.
Example:
1 x 143,613,569 = 143,613,569
and
-1 x -143,613,569 = 143,613,569
Notice both answers equal 143,613,569
With that explanation out of the way, let's continue. Next, we take the number 143,613,569 and divide it by 2:
143,613,569 ÷ 2 = 71,806,784.5
If the quotient is a whole number, then 2 and 71,806,784.5 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 | 143,613,569 | |
| -1 | -143,613,569 |
Now, we try dividing 143,613,569 by 3:
143,613,569 ÷ 3 = 47,871,189.6667
If the quotient is a whole number, then 3 and 47,871,189.6667 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 | 143,613,569 | |
| -1 | -143,613,569 |
Let's try dividing by 4:
143,613,569 ÷ 4 = 35,903,392.25
If the quotient is a whole number, then 4 and 35,903,392.25 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 | 143,613,569 | |
| -1 | 143,613,569 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 121 | 187 | 577 | 1,331 | 2,057 | 6,347 | 9,809 | 14,641 | 22,627 | 69,817 | 107,899 | 248,897 | 767,987 | 1,186,889 | 8,447,857 | 13,055,779 | 143,613,569 |
| -1 | -11 | -17 | -121 | -187 | -577 | -1,331 | -2,057 | -6,347 | -9,809 | -14,641 | -22,627 | -69,817 | -107,899 | -248,897 | -767,987 | -1,186,889 | -8,447,857 | -13,055,779 | -143,613,569 |
