(1 x 54) (2 x 27) (3 x 18) (6 x 9)
all of these are factors of 54
54 x 5 = 270 54 + 5 = 59 The two factors in question are therefore 54 and 5.
6 x 9 = 54
No factor of 54 is equal to 57.
54 has more than two factors.
There are two prime factors of 45, they are 3 and 5. The prime factors of 54 are 2 and 3.
You need at least two numbers before you can talk about common factors. 54 is only one number. As such, there is no real answer to your question. The factors of 54 are 1, 2, 3, 6, 9, 18, 27 and 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.
List 54 with one of its factors. The LCM of 54 and 27 is 54. Same with 54 and 6, 54 and 9, 54 and 3, etc.
54 and 16.
How about: 9+6 = 15
In order to show that a number is composite there is no need to find all the factors, we have to show only that it has more than two factors. 54 is divisible by 2, 3, 6 etc. which clearly shows that it has more than two factors.
54 is a composite number because it has more than two factors
