They are 2 and 5
The prime numbers (factors) of 80 are: 2 and 5
Two of the factors of 80 are prime numbers: 2 and 5.
A prime number has no other factors except itself and 1. There are three numbers between 80 and 100 that are prime: 83, 89 and 97.
There are 5 prime numbers from 60 to 80:61, 67, 71, 73 and 79
There are no prime numbers between 70 and 80 because all the numbers in that range have factors other than 1 and themselves. For example, 72 can be divided evenly by 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36, so it is not a prime number. Similarly, all the other numbers between 70 and 80 have multiple factors, making them composite numbers.
The prime numbers between 80 and 90 are 83 and 89.
The prime factorization of 80 is 2^4 * 5. This means that 80 can be expressed as the product of the prime numbers 2 and 5 raised to certain powers. In this case, 2 is raised to the power of 4 and 5 is raised to the power of 1.
Prime numbers between 71 to 80 = 73 and 79 Therefore there are 2 prime numbers between 71 to 80.
There are two which are 2 and 5 because 2*2*2*2*5 = 80
The prime factors of 80 are 2 and 5. For them to be common, they need to be compared to another set of prime factors.
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.
To find the prime factors of a number, start with any two factors and keep factoring the numbers until all factors are prime. 80 2 x 40 2 x 2 x 20 2 x 2 x 2 x 10 2 x 2 x 2 x 2 x 5 = 80
