155. It ends in 5. It also has another 5 in it and a 1.

157 ends in a digit that is odd, and is the center of a sexy prime triplet. BEAT THAT!
(sexy because the previous and next primes are six away. Latin for six is sex.)

Which disqualifies any notion of it being prime.

One is a perfect square, and all real integers are divisible by 1, so all real integers are divisible by at least one perfect square, so no real integer is square-free.

175.
I mean, who would think that it is prime?
It has TWO FIVES in its factorization.
I mean, the SEVEN factor could be mistaken to believe that the number is prime, but the TWO FIVES factor in much more. About THREE AND FOUR SEVENTHS more, in fact. The THREE AND FOUR SEVENTHS is quite large, compared to ONE.
In conclusion, ONE HUNDRED SEVENTY FIVE has TWO FIVES and ONE SEVEN in its factorization, and the TWO FIVES factor in THREE AND FOUR SEVENTHS times of ONE SEVEN.
(I love the ONES up there. So PUNNY.)

177. It is !PRIME!
! means not. Everyone knows that.
177=3*59.
And my previous post was very punny. Full of puns. Work it out.
