Which of the following numbers are co-prime?

Coprime numbers are numbers that have only 1 as their HCF. 18 and 35 have no common factors, Therefore, 18 and 35 are coprime numbers. As they have no common factors, 15 and 37 are co-prime numbers. As they have a common factor 5, hence, 30 and 415 are not co-prime.

What are the co-prime numbers between 1 to 100?

(2,3), (3,5), (5,7), (11,13), (17,19), (21,22), (29,31), (41,43), (59,61), (71,73), (87,88), (99,100), (28,57), (13,14), these are some of coprime numbers from 1 to 100.

Are Coprime numbers 81 and 16?

(f) 81 and 16

Since both have only one common factor, i.e., 1, therefore, they are co-prime numbers.

Which of the following is pair of co-prime numbers?

Consider a set of two numbers, if they have no positive integer that can divide both, other than 1, the pair of numbers is co-prime. For option (a), 14 and 35: The factors of 14 are 1, 2 and 7 and the factors of 35 are 1, 5 and 7. Here 14 and 35 have two common factors: they are 1 and 7.

What is co-prime example?

For example, the integers 6, 10, 15 are coprime because 1 is the only positive integer that divides all of them. If every pair in a set of integers is coprime, then the set is said to be pairwise coprime (or pairwise relatively prime, mutually coprime or mutually relatively prime).

Class 6 - Exercise 3.4 - Q 4 | Which of the following is co prime numbers

What is co-prime for Class 6?

Any set of numbers which do not have any other common factor other than 1 are called co-prime or relatively prime numbers. This shows that 5 and 6 have no common factor other than 1. Therefore, they are co-prime numbers.

What is co-prime number Class 10?

Co-prime Numbers. Co-prime numbers are pairs of numbers that do not have any common factor other than 1. There should be a minimum of two numbers to form a set of co-prime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are co-prime numbers.

Is 23 and 92 are Coprime?

No, 92 is not a prime number. The number 92 is divisible by 1, 2, 4, 23, 46, 92. For a number to be classified as a prime number, it should have exactly two factors. Since 92 has more than two factors, i.e. 1, 2, 4, 23, 46, 92, it is not a prime number.

Is 18 and 25 are Coprime numbers?

Answer: Yes (18,25) is a coprime as they are in simplest form and dont have any othaer factor except 1.

Is 9 and 28 co-prime number?

Explanation: coprime numbers have gcd 1. so 9 and 28 are coprime numbers.

Which of the following numbers are co-prime d 17 and 68 e 216 and 215 F 81 and 16?

Therefore, 17 and 68 are not co-prime. The common factor of 216 and 215 is only 1. Therefore, 216 and 215 are co-prime. The common factor of 81 and 16 is only 1.

Is 16 a co-prime number?

From above it is clear that 15 and 16 are co-prime because common factor is 1. Hence pairs 15 and 16, 16 and 21, 15 and 28 are co-primes.

What are the co-prime numbers between 1 to 50?

Answer: 3 is the co prime no.

Which of the following are pairs of co-prime 8 14?

1 Answer. ∴ 8 and 14 are not a pair of co-prime numbers. ∴ 4 and 5 are a pair of co-prime numbers.

Is 9 and 10 are Coprime number?

9 and 10 are the coprime numbers .

Is 4 and 9 are Coprime numbers?

Relatively prime numbers ( coprimes ) are numbers that share no common divisor (except 1). Numbers 4 and 9 share the number 1 as the only common divisor and so are coprimes .

Is 4 and 5 a co-prime number?

Another example is 4 and 5: 4 = 2*2*1; 5 = 5*1 (Prime). The only common factor is 1, so they are coprime.
