Sure! I can help you check your answers.
1. LCM of 10 and 18 is 180; False
To find the least common multiple (LCM) of two numbers, you need to factorize them and then multiply their common factors. The prime factorization of 10 is 2 * 5, and the prime factorization of 18 is 2 * 3 * 3. To find the LCM, we multiply the highest power of each prime factor. Therefore, the LCM of 10 and 18 is 2 * 3 * 3 * 5 = 90. So, the answer is False.
2. LCM of 8 and 30 is 120; True
Again, factorizing the numbers gives us 8 = 2 * 2 * 2 and 30 = 2 * 3 * 5. The LCM is the product of the highest power of each prime factor: 2 * 2 * 2 * 3 * 5 = 120. So, your answer is True.
3. LCM of 3 and 4 is 12; True
The prime factorization of 3 is 3, and the prime factorization of 4 is 2 * 2. The LCM is the product of the highest power of each prime factor: 2 * 2 * 3 = 12. Your answer is True.
4. LCM of 42 and 28 is 168; True
The prime factorization of 42 is 2 * 3 * 7, and the prime factorization of 28 is 2 * 2 * 7. The LCM is 2 * 2 * 3 * 7 = 84. So, the answer is False.
5. LCM of 9 and 15 is 45; True
The prime factorization of 9 is 3 * 3, and the prime factorization of 15 is 3 * 5. The LCM is 3 * 3 * 5 = 45. Your answer is True.
Based on the explanations above, your answers are:
1. False
2. True
3. True
4. False
5. True
