the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3

It is: 126

the least common multiple of 42,56, and 140 is 840.

In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.

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

the least common multiple of 42,56, and 140 is 840.

Take 30/42, for example. The prime factorization of the numerator (30) is 2 x 3 x 5. The prime factorization of the denominator (42) is 2 x 3 x 7. This will help you find the GCF or the LCM.

The LCM is: 840

No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7

In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.

We're not sure what you mean by the lmm. Generally, people ask for the LCM (least common multiple) but to find that, you need at least two numbers to compare. The prime factorization of 42 is 2 x 3 x 7.

No, 21 is not prime.
