3 x 5
Since 15 is a multiple of 3, it is automatically the LCM.
3 = 3
15 = 3*5
LCM(3, 15) = 3*5 = 15
The prime factorization of 4 is 2 x 2. It is not possible to find the LCM of a single number.
That appears to be the prime factorization of 14175. If you compare that to the prime factorization of another number, you will be able to find the LCM between the two.
The LCM of the given three numbers using prime factorization is 25200
To find both you start by doing a prime factorization, but then you do something a little different.
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
Prime factorization of 33 = 3 x 11 Prime factorization of 26 = 2 x 13 Nothing is common in the prime factorization of both numbers so LCM is equal to their product. LCM(33, 26) = 858.
Two or more numbers are needed to find their LCM
3 and 17 are both prime. Any time you have prime numbers, you multiply them together to get the LCM.
What is the prime authorization for LCM of 18,24
You have written the prime factorization for 432. You need at least two numbers to find an LCM.
Two or more numbers are normally needed to find the LCM
