There are many benefits to timing your practice, including:

If m is divisible by 3, how many prime factors does m have? 1). m/3 is divisible by 3. 2). m/3 has two different prime factors.

(1) m is divisible by 3 and m/3 is divisible by 3, this means m is divisible by 9

possible m values = {9,18,27...} 9 has 2 PF (3 X3) , 18 has 3 PF ( 2X3X3) Insuff

(2) m is divisible by 3 { 3,6,9,12,15,18...} and m/3 has two diff prime factors .

Does it mean that m/3 has only 2 different prime factors such as ( 2 and 3) or can it be (2 , 2 and 3) still be two different prime factors. It seems the later but confused.

If m is divisible by 3, how many prime factors does m have? 1). m/3 is divisible by 3. 2). m/3 has two different prime factors.

1) is insufficient since clearly m can be 21[3],27[3],54[4] etc 2)m/3 has 2 diff prime factors means that 3,2 or 2,7 means m has 3 prime factors IMO B even im confused as to 2 prime factors(which are diff) of or set of two diff prime factors

whats the source of this question?can we expect such Q in GMAT
