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 75,518,069, 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 | 75,518,069 | |
-1 | -75,518,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,518,069.
Example:
1 x 75,518,069 = 75,518,069
and
-1 x -75,518,069 = 75,518,069
Notice both answers equal 75,518,069
With that explanation out of the way, let's continue. Next, we take the number 75,518,069 and divide it by 2:
75,518,069 ÷ 2 = 37,759,034.5
If the quotient is a whole number, then 2 and 37,759,034.5 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 | 75,518,069 | |
-1 | -75,518,069 |
Now, we try dividing 75,518,069 by 3:
75,518,069 ÷ 3 = 25,172,689.6667
If the quotient is a whole number, then 3 and 25,172,689.6667 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 | 75,518,069 | |
-1 | -75,518,069 |
Let's try dividing by 4:
75,518,069 ÷ 4 = 18,879,517.25
If the quotient is a whole number, then 4 and 18,879,517.25 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 | 75,518,069 | |
-1 | 75,518,069 |
If you did it right, you will end up with this table:
1 | 11 | 6,865,279 | 75,518,069 |
-1 | -11 | -6,865,279 | -75,518,069 |
