The prime factorization of the LCM will contain all the prime factors of the two original numbers. When the original numbers don't have any prime factors in common, (the GCF is 1) the LCM will be their product. When the two original numbers have prime factors in common (the GCF is 2 or more) the duplicates will be discarded and the LCM will be less than their product.
There are 35 prime numbers less than 150.
There are no negative prime numbers.
There are 27 prime numbers less than 102.
There are 15 prime numbers less than 50

Prime numbers, except 2, are always odd (they would not be prime if they were even cos they would be divisible by 2.) 1 less than any odd number must be an even number.
If none of the prime factors are in common, the LCM will be the product of the two.
The higher you get, the more chances there are of a number being a multiple of something other than 1.
There are 35 prime numbers less than 150.
There are 25 prime numbers less than 100
There are 46 prime numbers less than 200.
The prime numbers less then 86 are; 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79 and 83.
70, it is a multiple of 2 and 7 is more than 50 but less than 100 and 2*5*7=70 and all those numbers are prime.
There are no negative prime numbers.
