hey guys, im a student engineer and have found that the laws we use are primarily based off of stats. this has led me to an interest in number theory and groupings. I was hoping someone could help me with somehing, i would like to know the relevance of the first 3 primes(2,3,5) to math in general. to be more specific, do the first three three primes play a significant role in number theory? I feel like i am being vague, so maybe i should ask, does being a multiple of 2, 3 or 5, or a power of one of these three give a number any special properties?
