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 152,052,103, 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 | 152,052,103 | |
| -1 | -152,052,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,052,103.
Example:
1 x 152,052,103 = 152,052,103
and
-1 x -152,052,103 = 152,052,103
Notice both answers equal 152,052,103
With that explanation out of the way, let's continue. Next, we take the number 152,052,103 and divide it by 2:
152,052,103 ÷ 2 = 76,026,051.5
If the quotient is a whole number, then 2 and 76,026,051.5 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 | 152,052,103 | |
| -1 | -152,052,103 |
Now, we try dividing 152,052,103 by 3:
152,052,103 ÷ 3 = 50,684,034.3333
If the quotient is a whole number, then 3 and 50,684,034.3333 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 | 152,052,103 | |
| -1 | -152,052,103 |
Let's try dividing by 4:
152,052,103 ÷ 4 = 38,013,025.75
If the quotient is a whole number, then 4 and 38,013,025.75 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 | 152,052,103 | |
| -1 | 152,052,103 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 953 | 991 | 6,671 | 6,937 | 21,919 | 22,793 | 153,433 | 159,551 | 944,423 | 6,610,961 | 21,721,729 | 152,052,103 |
| -1 | -7 | -23 | -161 | -953 | -991 | -6,671 | -6,937 | -21,919 | -22,793 | -153,433 | -159,551 | -944,423 | -6,610,961 | -21,721,729 | -152,052,103 |
