To find the Least Common Multiple (LCM) of 7, 14, and 21, we first need to factorize each number. The prime factors of 7 are 7, of 14 are 2 x 7, and of 21 are 3 x 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers. Therefore, LCM(7, 14, 21) = 2 x 3 x 7 = 42.

What is the prime factorization of 71421 use the prime factors what is the LCM and GCF of each number?
The prime factorization of 71421 is 3 x 7 x 19 x 179 but that's probably not what we're dealing with here. 7 2 x 7 = 14 3 x 7 = 21 The LCM and GCF refer to the set as a whole, not the individual numbers. The GCF of 7, 14, 21 is 7 The LCM of 7, 14, 21 is 42

What is the LCM of 6 7 and 21?
The Least Common Multiple (LCM) of 6, 7, and 21 is the smallest multiple that is divisible by all three numbers. To find the LCM, you need to factorize each number into its prime factors: 6 = 2 x 3, 7 = 7, and 21 = 3 x 7. Then, you take the highest power of each prime factor that appears in any of the factorizations: 2 x 3 x 7 = 42. Therefore, the LCM of 6, 7, and 21 is 42.
