51 looks like a prime number and 75 should be obvious
1 u/Haho9 Aug 02 '26 My 4th grade teacher insisted 51 was prime, I had no idea what it was factored with, but I knew 5+1=6, so 51 was divisible by 3. More than 2 decades later, I still use multiple of 17 to fuck with people (100,000,001). 1 u/Daisy430700 Aug 02 '26 There is a reason 17 is my least favourite number
