Answer 2

What is the awnser

Answer 3

To find the Least Common Multiple (LCM) of 4, 7, 12, and 21, you first need to find the prime factorization of each number.

4 = 2^2, 7 = 7^1, 12 = 2^2 * 3^1, and 21 = 3^1 * 7^1.

Now, identify the highest power of each prime factor that appears in any of the factorizations: 2^2, 3^1, and 7^1.

Finally, multiply these highest powers together to find the LCM: LCM(4, 7, 12, 21) = 2^2 * 3^1 * 7^1 = 84.

Answer 4

Oh, isn't that a happy little question! To find the Least Common Multiple (LCM) of 4, 7, 12, and 21, we look for the smallest number that these numbers can all divide into evenly. The LCM of these numbers is 84. Just like painting a beautiful landscape, finding the LCM can be a peaceful and rewarding experience.
