CCF-201709-5-除法 python运行超时如何解决？换种算法还是？

Question

CCF提交30分：

 a = list(map(int,input().split()))
b = list(map(int,input().split()))
sum = 0
while a[1]>0:
    c = list(map(int,input().split()))
    if c[0]==1:
        for i in range(c[1],(c[2]+1)):
            if b[i-1]%c[3] == 0:
                b[i-1]=b[i-1]/c[3]
        a[1]-=1
    elif c[0]==2:
        for i in range(c[1],(c[2]+1)):
            sum += b[i-1]
        print(round(sum))
        sum = 0
        a[1]-=1
