1: Find all n, 1<=n<=7770, n divisible by 7, n not div. by k if 7 doesn't divide k &
Help in combinatorics exercise
Hey everyone I'm stuck in the exercise, I will be happy to work out a solution
Find the number of integers n, where 1 < n < 7770, which have the following attributes:
. . .a. n is divisible by 7
. . .b. for any natural number k such that \(\displaystyle k\, \neq\, 7\, \leq\, k\, \leq\, 10\),
. . . . .it is true that n is not divisible by k
Thanks friends.
