Answer:
80 is not a Prime number. It is a composite number.
Definition:
A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.
Explanation:
Any number ending in 0, 2, 4, 6, or 8 is evenly divisible by 2, so it has 2 as a factor. 80 is also divisible by 2, so it is a composite number.
How about 81 or any number that is not a prime number.
The number is not COMPOSITE. Instead, it is a prime number.
ANSWER: 70 and 80 are not prime numbers. They are composite numbers:70 is a composite number because the factors of 70 other 1 and itself (70) are 2, 5, 7, 10, 14, and 35.80 is also a composite number because the factors of 80 other 1 and itself (80) are 2, 4, 5, 8, 10,16, 20, and 40.
Composite (the only even number that is prime is2).
Composite
How about 81 or any number that is not a prime number.
No primes are composite. The prime factors of 80 are 2 and 5.
No. All even numbers are composite except the number 2.
All even numbers greater than 2 are composite.
composite 80=2*2*2*2*5
It is not a prime number, it is a composite number.
It is prime
86 is not a prime number, so is a composite.
It is a Prime number, and therefore not a composite number.211 is a prime number.
No 168 is not a prime number it is a composite number
The number is not COMPOSITE. Instead, it is a prime number.
eighty is a composite number since it has the divisors of 16 and 5, 2 and 40,etc... in addition to 1 and its self (80).
