WebSolution: Given number = 449. To check whether a number 449 is divisible by 7, follow the below steps. Step 1: Double the unit digit = 9 x 2 = 18. Step 2: Take the difference between the remaining part of the given number and the result obtained from step 1. (i.e., 18) = 44 – 18. = 26, which is not a multiple of 7. WebClass group examples. What is the class group of the ring of integers Rin K= Q(p 10)? Solution. Since 10 = 2mod4, the ring Ris Z[p 10]. Thus ( R) = p 10. By the Minkowski bound Cis generated by factors of primes less than = (4=ˇ)( R) which is itself less than 4=3 p 10 which is less than 5. Thus we only have to factor (2) and (3).
