$6×10=3×2×2×5$ so three distinct factors are $3,2,5$ hence correct answer is $\boxed{3}$

$60 = 2 ^ { 2 } \times 3 \times 5$ , so $\boxed { 3 }$ prime factors are in $6 \times 10$ .

$6 \times 10 = 3 \times 2 \times 5 \times 2$

2, 3 ,5 are the factors so the answer is $\boxed{3}$

6 10=3 2^2*5. We count number of prime factors(ignore the power) 2,3,5 are the factors so the answer is 3
