What two numbers multiply to equal 54?
54 = 1 x 54, 2 x 27, 3 x 18, 6 x 9
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 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 are the two prime numbers that equal 54?
The only two prime numbers that multiply to equal 54 are 3 and 18. Prime numbers are integers greater than 1 that have no divisors other than 1 and themselves. In this case, 3 is a prime number because it is only divisible by 1 and 3, and 18 is not a prime number as it has divisors other than 1 and 18.
