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 146,103,049, 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 | 146,103,049 | |
| -1 | -146,103,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,103,049.
Example:
1 x 146,103,049 = 146,103,049
and
-1 x -146,103,049 = 146,103,049
Notice both answers equal 146,103,049
With that explanation out of the way, let's continue. Next, we take the number 146,103,049 and divide it by 2:
146,103,049 ÷ 2 = 73,051,524.5
If the quotient is a whole number, then 2 and 73,051,524.5 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 | 146,103,049 | |
| -1 | -146,103,049 |
Now, we try dividing 146,103,049 by 3:
146,103,049 ÷ 3 = 48,701,016.3333
If the quotient is a whole number, then 3 and 48,701,016.3333 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 | 146,103,049 | |
| -1 | -146,103,049 |
Let's try dividing by 4:
146,103,049 ÷ 4 = 36,525,762.25
If the quotient is a whole number, then 4 and 36,525,762.25 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 | 146,103,049 | |
| -1 | 146,103,049 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 97 | 697 | 1,649 | 2,161 | 3,977 | 36,737 | 67,609 | 88,601 | 209,617 | 1,506,217 | 3,563,489 | 8,594,297 | 146,103,049 |
| -1 | -17 | -41 | -97 | -697 | -1,649 | -2,161 | -3,977 | -36,737 | -67,609 | -88,601 | -209,617 | -1,506,217 | -3,563,489 | -8,594,297 | -146,103,049 |
