## What is relatively prime to 20?

Relatively Prime.

Two or more natural numbers are relatively prime if they have a greatest common factor (gcf) of 1.

…

Since the greatest common factor of 20 and 63 is 1, 20 and 63 are relatively prime..

## Are 15 and 21 Coprime numbers?

1 Answer. Hence pairs 15 and 16, 16, 21, 15, 28 are co-prime number.

## Are 4 and 15 relatively prime?

relatively prime (unrelated, strangers)…OVERLAPPING.41572810538431554201575May 31, 2020

## Is 14 and 21 relatively prime?

In number theory, two integers a and b are coprime, relatively prime or mutually prime if the only positive integer that evenly divides (is a divisor of) both of them is 1. … On the other hand, 14 and 21 are not coprime, because they are both divisible by 7.

## Are 4 and 9 relatively prime?

The only common divisor between 4 and 9 is number 1, so 4 and 9 are “prime with respect to each other”. Regarding the number 15 and 21, they are not relatively primes, since besides number 1 they also have number 3 as a common divisor.

## Are 12 and 15 relatively prime numbers?

Two integers are relatively prime (or coprime) if there is no integer greater than one that divides them both (that is, their greatest common divisor is one). For example, 12 and 13 are relatively prime, but 12 and 14 are not.

## What is the HCF of two Coprime numbers?

1The HCF of two co-prime numbers is 1.

## What is the LCM of 8 12 and 24?

Answer: LCM of 8 and 12 is 24. 2. What are the Factors of 8?

## Is 3 and 4 are Coprime?

The only common factor is 1 and hence they are 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.

## Which is the smallest prime number?

## Is 42 and 77 relatively prime?

7 is the number which divides 42 and 77 both. … So, they are relatively prime numbers.

## Is 15 and 37 Coprime numbers?

Yes, 15 and 37 are Co- prime numbers.

## What is the GCF of 12 and 18?

In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18.

## Are 9 and 10 Coprime numbers?

9 and 10 are the coprime numbers .

## Are 4 and 5 Coprime numbers?

As an example, 6 and 35 are coprime, because the factors of 6, 2 and 3, do not divide 35 evenly. On the other hand, 6 and 27 are not coprime, because 3 divides both 6 and 27. Another example is 4 and 5: 4 = 2*2*1; 5 = 5*1 (Prime). The only common factor is 1, so they are coprime.
