2 x 3 x 3 = 18
3 x 7 = 21
2 x 3 x 3 x 7 = 126, the LCM
It is: 72
The prime factorizations are: 5 3 * 3 * 2 2 * 5 Eliminating the common factors, we get 3 * 3 * 2 * 5 Simplifying gives us 90 The LCM of 5, 18, and 10 is 90.
Since 13 is a prime number, and 18 is the LCM of 9 and 18, then 13*18 = 234 is the LCM of 13, 9, and 18.
The greatest common factor of 12, 18, and 28 is 2.The prime factorization of 12 is 2*2*3The prime factorization of 18 is 2*3*3The prime factorization of 28 is 2*2*7So the greatest common factor of the set is 2.
If you want to find the LCM of two numbers, you first need to break those numbers down into their prime factors: 27=3x3x3 18=3x3x2 The next step is to discard the duplicate entries of any common prime factors. In this case, both numbers have two 3s in their prime factors, so we can discard 2 of these, leaving us with 3,3,3 and 2. Multiply all these together for the LCM: 3x3x3x2 = 54 So the lowest common multiple of 27 and 18 is 54.
To find the LCM of three numbers you first have to break them down into their prime factors. In this case: 27 = 3x3x3 18 = 2x3x3 10 = 2x5 The next step is to identify any duplicates and cross them out. In this case two numbers share two 3s as prime factors, and two numbers share a 2 as prime factor. That leaves us with 3, 3, 3, 2 and 5 as the prime factors to work with. Multiplying these together gives 270, and so the LCM of 27, 18 and 10 is 270.
The LCM of 60 and 18 is 180
The prime factorizations are: 5 3 * 3 * 2 2 * 5 Eliminating the common factors, we get 3 * 3 * 2 * 5 Simplifying gives us 90 The LCM of 5, 18, and 10 is 90.
The prime factorization of 18 is 2*3*3 The prime factorization of 27 is 3*3*3 The prime factorization of 90 is 2*3*3*5
18 in pime exponents is 2*32 24 in prime exponents is 23*3 LCM: 23*32 = 72
It is: 144
since 29 is a prime simply 18*29=522
To find the lowest common multiple for numbers, prime factor each the use each prime number the number of times it appeared the most in each number. 18=2x3x3 20=2x2x5 30=2x3x5 lcm=2x2x3x3x5=180
Since 13 is a prime number, and 18 is the LCM of 9 and 18, then 13*18 = 234 is the LCM of 13, 9, and 18.
prime factors of 18 are 2 and 32 prime factors of 24 are 23 and 3 prime factors of 42 are 2, 3 and 7 LCM = 23*32*7 = 504
13 is a prime number and thus the the LCM of 13 and any number is 13 times that number. The LCM is: 234
The greatest common factor of 12, 18, and 28 is 2.The prime factorization of 12 is 2*2*3The prime factorization of 18 is 2*3*3The prime factorization of 28 is 2*2*7So the greatest common factor of the set is 2.
It is: 32*25 = 288
