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 350,145,689, 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 | 350,145,689 | |
| -1 | -350,145,689 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 350,145,689.
Example:
1 x 350,145,689 = 350,145,689
and
-1 x -350,145,689 = 350,145,689
Notice both answers equal 350,145,689
With that explanation out of the way, let's continue. Next, we take the number 350,145,689 and divide it by 2:
350,145,689 ÷ 2 = 175,072,844.5
If the quotient is a whole number, then 2 and 175,072,844.5 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 | 350,145,689 | |
| -1 | -350,145,689 |
Now, we try dividing 350,145,689 by 3:
350,145,689 ÷ 3 = 116,715,229.6667
If the quotient is a whole number, then 3 and 116,715,229.6667 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 | 350,145,689 | |
| -1 | -350,145,689 |
Let's try dividing by 4:
350,145,689 ÷ 4 = 87,536,422.25
If the quotient is a whole number, then 4 and 87,536,422.25 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 | 350,145,689 | |
| -1 | 350,145,689 |
If you did it right, you will end up with this table:
| 1 | 37 | 43 | 101 | 1,591 | 2,179 | 3,737 | 4,343 | 80,623 | 93,697 | 160,691 | 220,079 | 3,466,789 | 8,142,923 | 9,463,397 | 350,145,689 |
| -1 | -37 | -43 | -101 | -1,591 | -2,179 | -3,737 | -4,343 | -80,623 | -93,697 | -160,691 | -220,079 | -3,466,789 | -8,142,923 | -9,463,397 | -350,145,689 |
