A positive integer has exactly eight positive divisors. If two of the divisors are 21 and 35, what is the number? NOTE: For some integer n, a divisor of n is a non-zero integer that divides exactly into n leaving a remainder of 0. For example: 3 is a divisor of 18 since, 18 ÷ 3 = 6 remainder 0. 4 is not a divisor of 18, since 18 ÷ 4 = 4 remainder 2.
