Such questions do not exist, but it's unclear how I would 'prove' this absence to anyone. In my wide experience, no official questions depend on having the 3-digit primes memorized.

I am GMAT expert and I have explained thousands of GMAT math practice questions. Not much more than that: certainly three-digit prime numbers are unnecessary.Дў) My friend, you are a student. This would be the very small set, a set of 15 prime numbers. I assume you acknowledge the mathematical mistakes in your original post.ДЎ) What I said was that it was important memorize the prime numbers up to 30, that is, the set of prime numbers less than 30. Actually 1000 is NOT equal to 997 ! ) your suggestion and writing doesn't have any GOOD combination at all.ДЄctually, we should 'think or calculate twice, and post once!' You said upto 30th prime number is enough for GMAT but you gave me a list of upto 997 ( also you mistakenly said it is upto 1000. But, this 30th prime number is still 3 digit prime! Which is confusing, isn't it?Дў/ how did you be sure that GMAC will not ask 3 digit primes in the exam directly or indirectly? Can you please show me any evidence regarding THIS 3 digit primes?ДЈ/ i am student trying to take GMAT. And you also said to memorize up to 30th prime number is enough.

They are:ДЎ/ you said not to memorize 3 digit prime numbers. No, it doesn't make sense to me because of some confusing suggestions. In this web-based format, we might say, think or calculate twice, and post once. It's an old saying among carpenters: measure twice, cut once. Think very carefully about what you put out into the world and how it might reflect on you.

My friend, your post is both not useful and incorrect. You list as prime numbers three non-prime numbers: No one needs to memorize three-digit prime numbers.ДЇurthermore, there are multiple mistakes in your list. First of all, no one needs to memorize prime numbers this high-for the GMAT, knowing the prime numbers up to 30 probably would be adequate, and up to 100 would be thorough. My friend, it is unclear why you posted this.
