The word 'denominator' refers to the bottom number of a fraction. For example, 7 is the denominator of the fraction 3/7. As 16 and 25 are not fractions then there is no denominator of any kind.
If the question refers to the Least (or Lowest) Common Multiple (LCM), then determine the prime factors of both numbers.
16 = 2 x 2 x 2 x 2 = 24
25 = 5 x 5 = 52
The LCM is the product of the highest power of each prime factor.
The LCM of 16 and 25 is therefore 24 x 52 = 16 x 25 = 400
A common denominator, though not the least, is 150.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
It is 100
the answer is five
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
A common denominator, though not the least, is 1700.
A common denominator, though not the least, is 1700.
A common denominator, though not the least, is 150.

If you mean Least Common Multiple; it is 50.
