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 130,025,003, 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 | 130,025,003 | |
-1 | -130,025,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,025,003.
Example:
1 x 130,025,003 = 130,025,003
and
-1 x -130,025,003 = 130,025,003
Notice both answers equal 130,025,003
With that explanation out of the way, let's continue. Next, we take the number 130,025,003 and divide it by 2:
130,025,003 ÷ 2 = 65,012,501.5
If the quotient is a whole number, then 2 and 65,012,501.5 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 | 130,025,003 | |
-1 | -130,025,003 |
Now, we try dividing 130,025,003 by 3:
130,025,003 ÷ 3 = 43,341,667.6667
If the quotient is a whole number, then 3 and 43,341,667.6667 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 | 130,025,003 | |
-1 | -130,025,003 |
Let's try dividing by 4:
130,025,003 ÷ 4 = 32,506,250.75
If the quotient is a whole number, then 4 and 32,506,250.75 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 | 130,025,003 | |
-1 | 130,025,003 |
If you did it right, you will end up with this table:
1 | 23 | 5,653,261 | 130,025,003 |
-1 | -23 | -5,653,261 | -130,025,003 |
