Any number ending in a 5, other than the number 5 itself, is composite.
It is neither. The concept of prime or composite is relevant for whole numbers greater than 1.
Both of these numbers are prime numbers.
Composite.because it has factors other then one and itself (5*5*3).
no, because a composite number can be found by multiplying three prime numbers. 3*2*5 = 30, and 30 is a composite number and also has 3 prime factors. Every prime number has 1 prime factor by the way, itself. 1 is neither prime nor composite.
155 five is composite. It is composite because it has 5 as a factor. The only number that can be neither prime nor composite is 1.
1155 is obviously a multiple of 5 and a multiple of 11, so it is a composite number.
Any number ending in a 5, other than the number 5 itself, is composite.
It's prime becase only composite has 2 number
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 5 is prime.
155 is a composite number. Its factors are 1, 5, 31, and 155.
It is a prime.
It is neither. The concept of prime or composite is relevant for whole numbers greater than 1.
Both of these numbers are prime numbers.
15 is a composite number because it has more than two factors. Its factors are 1, 3, 5, and 15.15 is a composite number as it is divisible by 1, 3, 5 and 15.composite. 3*5=1515 is a composite number because it has more than 2 factors
5 is a prime number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100 2 and 5 are prime. 1 is neither. The rest are composite.
