How do you find the prime factorization of 18 and 21?
Draw the prime factorization table and put both the numbers on it. Find common prime factors and divide both of them writing the products down. Do this until the quotients are either 1 or any prime number. Write down all the factors used and it will be the prime factorization. Multiply them and you will find the LCM of the numbers. Here, 18,21 6,7...................(/3) Prime factorization=6*7*3 LCM=42*3=126
How can you use prime factorization to find the LCM of 15 and 21?
3 x 5 = 15 3 x 7 = 21 3 x 5 x 7 = 105, the LCM
What is the least common multiple of 9 21 and 7?
To find the least common multiple (LCM) of 9, 21, and 7, we first need to find the prime factorization of each number. The prime factorization of 9 is 3^2, 21 is 3*7, and 7 is a prime number itself. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 3^2 * 7 = 63. Therefore, the least common multiple of 9, 21, and 7 is 63.
What is the LCM of 14 21 and 27?
To find the Least Common Multiple (LCM) of 14, 21, and 27, we first need to find the prime factorization of each number. The prime factorization of 14 is 2 x 7, 21 is 3 x 7, and 27 is 3 x 3 x 3. Then, we identify the common and uncommon prime factors among the numbers. The LCM is calculated by multiplying the highest power of each prime factor present in any of the numbers, resulting in 2 x 3 x 3 x 7 = 126. Therefore, the LCM of 14, 21, and 27 is 126.
