Example: 30 and 42
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.
LCM is 96, which is the multiple of the highest power of prime factors in the given numbers (25 x 3).
The prime factorization of the LCM will contain all the prime factors of the two original numbers. When the original numbers don't have any prime factors in common, (the GCF is 1) the LCM will be their product. When the two original numbers have prime factors in common (the GCF is 2 or more) the duplicates will be discarded and the LCM will be less than their product.
Multiply them together.
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 of the given three numbers using prime factorization is 25200
You have written the prime factorization for 432. You need at least two numbers to find an LCM.
Prime factorization.
You need at least two numbers to find an LCM no matter what you use.
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.
You need at least two numbers to find an LCM no matter what method you choose.
The prime factorization of 4 is 2 x 2. It is not possible to find the LCM of a single number.
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
You need at least two numbers to find an LCM.
It doesn't matter which method you use. You still need at least two numbers to find an LCM. There is no LCM of 20.
The LCM of these numbers is 740. LCM is Least Common Multiple.
You need at least two numbers to find an LCM.
