Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
no take 3 for example. 3 6 9 3 x 3= 9 so that's composite.
There prime numbers
Since both 3 and 5 are prime numbers, only numbers that are multiples of its product are the numbers that are divisible by both. 15 is the LCM of 3 and 5 and hence all multiples of 15 are divisible by both 3 and 5
A number that is not a prime number is called a composite number because it can be made by multiplying prime numbers together. For example, 6 is a composite number that is the product of multiplying the prime numbers 2 and 3 together.
