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 143,926,825, 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 | 143,926,825 | |
| -1 | -143,926,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,926,825.
Example:
1 x 143,926,825 = 143,926,825
and
-1 x -143,926,825 = 143,926,825
Notice both answers equal 143,926,825
With that explanation out of the way, let's continue. Next, we take the number 143,926,825 and divide it by 2:
143,926,825 ÷ 2 = 71,963,412.5
If the quotient is a whole number, then 2 and 71,963,412.5 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 | 143,926,825 | |
| -1 | -143,926,825 |
Now, we try dividing 143,926,825 by 3:
143,926,825 ÷ 3 = 47,975,608.3333
If the quotient is a whole number, then 3 and 47,975,608.3333 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 | 143,926,825 | |
| -1 | -143,926,825 |
Let's try dividing by 4:
143,926,825 ÷ 4 = 35,981,706.25
If the quotient is a whole number, then 4 and 35,981,706.25 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 | 143,926,825 | |
| -1 | 143,926,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 863 | 953 | 4,315 | 4,765 | 6,041 | 6,671 | 21,575 | 23,825 | 30,205 | 33,355 | 151,025 | 166,775 | 822,439 | 4,112,195 | 5,757,073 | 20,560,975 | 28,785,365 | 143,926,825 |
| -1 | -5 | -7 | -25 | -35 | -175 | -863 | -953 | -4,315 | -4,765 | -6,041 | -6,671 | -21,575 | -23,825 | -30,205 | -33,355 | -151,025 | -166,775 | -822,439 | -4,112,195 | -5,757,073 | -20,560,975 | -28,785,365 | -143,926,825 |
