Q.1 If a number K = 42 × 25 × 54 × 135 is divisible by 3 a , then find the maximum value of a.

9450

2551500<br> if option not given then a max value of a would be 2551500*3 =7654500 as product of 42*25*54*135 = 7654500 and it going to be a factor of its own thus we can stretch value of a in 3a upto the value of divident
