 # Quick Answer: Is 4 And 8 A Coprime Number?

## Are 32 and 34 Coprime numbers Why?

When the HCF of two or more numbers is 1, then they are called co-prime numbers.

The HCF of 32 and 34 is 2, which ≠ 1.

So, they are not co-prime numbers.

Hope it helps..

## Is 4 a Coprime number?

Co prime numbers from 1 to 100 (75, 41) and so on. Also, we can write any number with the combination of 1 as a coprime pair such as (22, 1), (31, 1), (4, 1), (90, 1), (1, 100). In this way, many coprime numbers are defined from 1 to 100.

## 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.

## Are 2 and 15 Coprime numbers?

Consider any consecutive number such as 2, 3 or 3, 4 or 14 or 15 and so on; they have 1 as their HCF. The sum of any two co-prime numbers is always coprime with their product.

## What is the smallest prime number?

2Hardy as the last major mathematician to consider 1 to be prime. (He explicitly included it as a prime in the first six editions of A Course in Pure Mathematics, which were published between 1908 and 1933. He updated the definition in 1938 to make 2 the smallest prime.)

## What is the HCF of two Coprime number?
