Why is every multiple of 5 a composite number?
Not all (5 is prime) but every multiple of 5 greater than 5 is composite because they have more than two factors. Every multiple of any integer greater than one is composite.
Is Every multiple of 5 is composite?
Yes.
Is every multiple of 5 a composite number?
Yes because the five has gas
Is every multiple of 11 composite?
Every multiple of any number (except 0 or 1) is composite.
Is every multiple of 5 a composite number true or false?
False. A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. Every multiple of 5 is not a composite number, as 5 itself is a prime number with only two distinct positive divisors, 1 and 5.
Is every multiple of five composite?
Yes.
Is every multiple of 7 a composite numbers?
No. 7, itself, is a multiple of 7 [7 * 1 = 7] and it is not a composite.
Is every multiple of 7 composite?
Yes.
45 prime or composite?
Composite. This can be most easily seen by the fact that it ends in a 5, thus it is a multiple of 5, and since it is not itself 5, it is composite.
Is 1155 prime composite or neither?
1155 is obviously a multiple of 5 and a multiple of 11, so it is a composite number.
Is 45 prime or composite?
45 is a composite since it factors are 5 and 9.
What is the GCF of 108 and 5?
GCF of a prime number and a composite number is 1 if the composite number is not a multiple of the prime number. Here, 5 is a prime number and 108 is a composite number(not the multiple of 5). Therefore GCF of 108 and 5 is 1.
