What would be the ideal Common Denominator for 2 and 4?
The least common denominator is the least common whole number all of the numbers are divisible by. 8 can be divided by 1, 2, 4, and 8. 10 can be divided by 1, 2, 5, and 10. 11 is a prime number, this means it can only be divided by 1 and itself. Therefore the least common denominator for 8, 11, and 10 is 1.
A common denominator, though not the least, is 30.
