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 143,625,041, 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 | 143,625,041 | |
| -1 | -143,625,041 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,625,041.
Example:
1 x 143,625,041 = 143,625,041
and
-1 x -143,625,041 = 143,625,041
Notice both answers equal 143,625,041
With that explanation out of the way, let's continue. Next, we take the number 143,625,041 and divide it by 2:
143,625,041 ÷ 2 = 71,812,520.5
If the quotient is a whole number, then 2 and 71,812,520.5 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 | 143,625,041 | |
| -1 | -143,625,041 |
Now, we try dividing 143,625,041 by 3:
143,625,041 ÷ 3 = 47,875,013.6667
If the quotient is a whole number, then 3 and 47,875,013.6667 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 | 143,625,041 | |
| -1 | -143,625,041 |
Let's try dividing by 4:
143,625,041 ÷ 4 = 35,906,260.25
If the quotient is a whole number, then 4 and 35,906,260.25 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 | 143,625,041 | |
| -1 | 143,625,041 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 691 | 1,291 | 4,837 | 9,037 | 15,893 | 29,693 | 111,251 | 207,851 | 892,081 | 6,244,567 | 20,517,863 | 143,625,041 |
| -1 | -7 | -23 | -161 | -691 | -1,291 | -4,837 | -9,037 | -15,893 | -29,693 | -111,251 | -207,851 | -892,081 | -6,244,567 | -20,517,863 | -143,625,041 |
