Question

Which number is a multiple of 6?
(A) 2 (B) 3 (C) 42 (D) 1

Answer 1

A multiple of a number is any product of that number with another number. For 6, the first few multiples are 6 × 1, 6 × 2, 6 × 3, 6 × 4, 6 × 5 ... which are 6, 12, 18, 24, 30, and so on. 42 is a multiple of 6, since 6 × 7 = 42. So the answer is C. The other choices (2, 3, and 1) are factors of 6, not multiples. 

Answer 2

 C)

 

  Because 42 = 6 . 7
