First take smallest 6 numbers
2,2,2,2,2,2 = 64 then
2,2,2,2,2,3 = 96 then
If we increase any number then surely the product will be greater than 99.
St1: Clearly INSUFF
St2: Clearly INSUFF
j is for sure a multiple of 2,3 and 5 prime numbers
but k = 1000 is a multiple of only 2 and 5 prime number: SUFF
In case "different" removed then surely E. j could be 30,000, which include all factors of 1000 and could be 30, which have very few factors than 1000.
