Least common denominator: the smallest multiple or factor that is exactly divisible by every member of a set of numbers.

Factors of 25: 1, 5, 25

Factors of 30: 1,3,5,10,30

Shared factors of 25 and 30: 1,5

Therefore, the least common denominator would be 1 because it is the smallest factor shared between the two numbers.
