36 red pens and 60 blue pens must be put into identical bags with none left over. What is the greatest possible number of bags?

  1. 6 bags
  2. 10 bags
  3. 24 bags
  4. 12 bags
Show answer

Correct answer: 12 bags

We need the greatest common factor of 36 and 60. 36 = 2² × 3² and 60 = 2² × 3 × 5. So the factor = 2² × 3 = 12.
