What is the LCM for 6 15 and 21?

Answer 1

To find the Least Common Multiple (LCM) of 6, 15, and 21, we first need to find the prime factorization of each number. The prime factorization of 6 is 2 x 3, 15 is 3 x 5, and 21 is 3 x 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2 x 3 x 5 x 7 = 210. Therefore, the LCM of 6, 15, and 21 is 210.

Answer 2

Oh, what a happy little question! To find the Least Common Multiple (LCM) of 6, 15, and 21, we look for the smallest number that all three numbers can divide into evenly. First, we list the multiples of each number: 6 (6, 12, 18, 24...), 15 (15, 30, 45...), and 21 (21, 42...). The smallest number they all share is 30, so the LCM of 6, 15, and 21 is 30.

Answer 3

Oh honey, the least common multiple (LCM) for 6, 15, and 21 is 30. It's like finding a good wine to pair with your meal - you want something that goes well with all three dishes. So, in this math equation menu, 30 is the perfect LCM that complements all three numbers. Cheers to that!

Answer 4

When finding the LCM of three numbers, you first need to break them down into their prime factors:

6 = 2x3

7 = 7

15 = 3x5

The next step is to identify any common factors, and cross off the duplicates. In this case, two numbers have 3 as a factor. Crossing this off leaves us with 2, 3, 5 and 7. Multiply those together and you get 210.

Thus the LCM of 6 7 and 15 is 210.
