What is the common factor of 54?
In order to find common factors you need two or more numbers. However, the factors of 54 (at least 2 numbers that can be multiplied evenly, or with no remainder, into 54) are: 1,2,3,6,9,18,27, and 54.
What is the LMC 54 and 63?
To find the LCM of two numbers, you need to first write them as their prime factors. In this case, 54 and 63 split to: 54 = 2x3x3x3 63 = 3x3x7 The next step is to identify any common factors. In this case, both numbers have two 3s as factors. Thus we can discard two of them. That leaves us with 2, 3, 3, 3 and 7. Multiply these factors together to get the LCM: 2x3x3x3x7 = 378. Thus the LCM of 54 and 63 is 378.
What is the greatest common factor of 50 and 54?
To work this out, you first have to break the two numbers into their prime factors: 50 = 2x5x5 54 = 2x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore the GCF of 50 and 54 is 2.
What is the HCF of18 and 54?
To find this, you first have to split the numbers into their prime factors: 18 = 2x3x3 54 = 2x3x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 and two 3s as prime factors. Multiply these together gives you: 2x3x3 = 18 Therefore the HCF of 18 and 54 is 18.
What is the factor 78 and 54?
