What Is The LCM Of Two Coprime Numbers?

Are 2 and 3 Coprime numbers?

For example, 2 and 3 are two prime numbers.

Factors of 2 are 1, 2, and factors of 3 are 1, 3.

The only common factor is 1 and hence is co-prime.

Any two successive numbers/ integers are always co-prime: Take any consecutive numbers such as 2, 3, or 3, 4 or 5, 6, and so on; they have 1 as their HCF..

What is the HCF of 12 and 16?

The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.

Is 15 and 37 Coprime numbers?

Factors of 15 are 1, 3, 5 and 15. Factors of 37 are 1 and 37. Therefore, 1 is the only common factor of 15 and 37 which means that 15 and 37 are co-prime.

What is the HCF of two Coprime numbers?

The HCF of two coprime numbers is always 1 . For example: 5 and 9 are coprime numbers and hence, HCF (5,9)=1 ( 5 , 9 ) = 1 .

What is Coprime number?

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1. … A set of integers can also be called coprime if its elements share no common positive factor except 1.

What is the LCM of 117?

Least common multiple (LCM) of 117 and 121 is 14157.

What is the HCF of 12 and 18?

Factors of 18 = 1, 2, 3, 6, 9 and 18. Therefore, common factor of 12 and 18 = 1, 2, 3 and 6. Highest common factor (H.C.F) of 12 and 18 = 6 [since 6 is the highest common factor].

What are the factors of 117?

117 is a composite number. 117 = 1 x 117, 3 x 39, or 9 x 13. Factors of 117: 1, 3, 9, 13, 39, 117. Prime factorization: 117 = 3 x 3 x 13, which can also be written 3² x 13.

What is 1 called if it is not a prime?

A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4.

Is 2 and 4 are Coprime number?

2 and 4 are not co prime numbers. Because co prime numbers are number which can only divisible by 1. … It is coprime number because they are only divisible by 1. Here 2 and 4 are divisible by 2.

Are two consecutive numbers Coprime?

Any two consecutive integers are always coprime. Sum of any two coprime numbers is always coprime to their product.
