Number Of Prime Factors [#permalink]  30 Aug 2010, 16:23
Hi,

If I'm faced with a question on counting the number of prime factors, do I assume unique or total?

eg. 12 has 2 2 3 as prime factors.. so does it have 2 prime factors or 3?

I'm going through some problems were I interpreted it as "total factors" as opposed to unique and I got all the related questions wrong b/c of that.

Krazo,

the question will specificaly ask you for the total of unique of prime factors, the total of prime factors, or the factors (eg the factors of 16 are 1,2,4,8,16)
Official questions rarely are ambiguous as they are screened multiple times through tests etc....

Thanks.. that's what I figured based on the OG guide, but doesn't hurt to make sure!
