The LCM of three different numbers is 120. Which of the following cannot be their HCF?

Explanation:-

LCM = 120 (given)
LCM is the product of one common factor and other different factors of the given numbers.
∴ Factorize the given LCM = 120 $$\frac{{\,\,\,{\text{2}} \times {\text{2}} \times {\text{3}} \times {\text{5}} \times {\text{2}}\,\,\,}}{{4\left( {3 \times 5 \times 2} \right)}}$$ = Here 4 is common factor (common factor is the HCF of the given number
∴ HCF = 4
So, for the given numbers the HCF should be multiple of 4
⇒ Hence go through options which is not a multiple of 4 is 35
Hence answer is 35
