To find the factors of 9 and 15, we can break them down: For 9, the factors are 1, 3, and 9. For 15, the factors are 1, 3, 5, and 15. The GCF (Greatest Common Factor) is 3, so circle that! Now, let’s list the multiples: For 4, the first 7 multiples are 4, 8, 12, 16, 20, 24, and 28. For 10, the first 7 multiples are 10, 20, 30, 40, 50, 60, and 70. The LCM (Least Common Multiple) is 20, so circle that!
