Ok, let's do some prime factoring:
2
2 * 2
11
Those are the prime factors of those numbers. Since 2 and 2 * 2 share a two, we can drop one 2, then multiply the rest... 2 * 2 * 11. 2 * 2 = 4. 4 x 11 = 44. 44 is the smallest number with the factors 2, 4 and 11.
11
1024
165
It is their LCM which is 330
That would be the square of a prime number, in this case, 11 x 11 = 121.
11
1024 has exactly eleven. 60 has twelve, so it has eleven as well.
1024
It is 11 which is a prime number whose factors are itself and one
165
44
5 and 11
number 1155
165
154
It is: 44
Prime numbers, raised to a power, have one more factor than their exponents. The smallest prime number is 2. 210 has eleven factors. 210 = 1024
