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 425,350,141, 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 | 425,350,141 | |
| -1 | -425,350,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,350,141.
Example:
1 x 425,350,141 = 425,350,141
and
-1 x -425,350,141 = 425,350,141
Notice both answers equal 425,350,141
With that explanation out of the way, let's continue. Next, we take the number 425,350,141 and divide it by 2:
425,350,141 ÷ 2 = 212,675,070.5
If the quotient is a whole number, then 2 and 212,675,070.5 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 | 425,350,141 | |
| -1 | -425,350,141 |
Now, we try dividing 425,350,141 by 3:
425,350,141 ÷ 3 = 141,783,380.3333
If the quotient is a whole number, then 3 and 141,783,380.3333 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 | 425,350,141 | |
| -1 | -425,350,141 |
Let's try dividing by 4:
425,350,141 ÷ 4 = 106,337,535.25
If the quotient is a whole number, then 4 and 106,337,535.25 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 | 425,350,141 | |
| -1 | 425,350,141 |
If you did it right, you will end up with this table:
| 1 | 47 | 79 | 97 | 1,181 | 3,713 | 4,559 | 7,663 | 55,507 | 93,299 | 114,557 | 360,161 | 4,385,053 | 5,384,179 | 9,050,003 | 425,350,141 |
| -1 | -47 | -79 | -97 | -1,181 | -3,713 | -4,559 | -7,663 | -55,507 | -93,299 | -114,557 | -360,161 | -4,385,053 | -5,384,179 | -9,050,003 | -425,350,141 |
