Find the odd one out: 

24, 42, 54, 62, 78

24 = $$2^3\times3^1$$ $$\Rightarrow$$ Number of factors = 4 x 2 = 8

42 = $$2^1\times3^1\times7^1$$ $$\Rightarrow$$ Number of factors = 2 x 2 x 2 = 8

54 = $$2^1\times3^3$$ $$\Rightarrow$$ Number of factors = 2 x 4 = 8

62 = $$2^1\times31^1$$ $$\Rightarrow$$ Number of factors = 2 x 2 = 4

78 = $$2^1\times3^1\times13^1$$ $$\Rightarrow$$ Number of factors = 2 x 2 x 2 = 8

Number of factors of all numbers except 62 is 8.

$$\therefore\ $$62 is the odd one among the given numbers.

Hence, the correct answer is Option C
