Class 6 Factor & Multiples, H.C.F Question

An instructor has a test bank consisting of 300 easy True/False questions, 200 difficult True/False questions, 500 easy multiple choice questions (MCQ) and 400 difficult multiple choice questions. If a questions is selected at random from the test bank, what is the probability that it will be an easy question given that it is a multiple choice question.

Every counting number has an infinite number of (a)factors (b) multiples prime factors (d) none of these

Define: (1) factor (2) multiple Give four examples of each.

Write a proper fraction with denominator a multiple of 5 and numerator a multiple of 6.

Using Euclid’s algorithm find the H.C.F. of 513 and 783

H.C.F. of co-prime numbers 4 and 15 was found as follows: 4=2\ *\ 2\ a n d\ 15=3\ *\ 5 Since there is no common prime factor. So, H.C.F. of 4 and 15 is 0. Is the answer correct? If not, what is the correct H.C.F.?
