## What is the GCF of 12 and 28?

4The biggest common factor number is the GCF number.

So the greatest common factor 12 and 28 is 4..

## What is the GCF of 18 and 28?

We found the factors and prime factorization of 18 and 28. The biggest common factor number is the GCF number. So the greatest common factor 18 and 28 is 2.

## What is the common factor of 17?

The two numbers which get multiplied and produce the result as 17, then these numbers are the factors of 17. Since 17 is a prime number, therefore it has only two factors, i.e. 1 and 17.

## What is the GCF of 16 and 68?

4Greatest common factor (GCF) of 16 and 68 is 4.

## What’s the GCF of 27 and 63?

Greatest common factor (GCF) of 27 and 63 is 9. We will now calculate the prime factors of 27 and 63, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 27 and 63.

## What is the GCF of 15 and 33?

We found the factors and prime factorization of 15 and 33. The biggest common factor number is the GCF number. So the greatest common factor 15 and 33 is 3.

## What is the GCF of 16 and 40?

8The GCF of 16 and 40 is 8.

## Is 18 a co prime number?

Yes, 18 and 35 are co-prime numbers. The factors of 18 are 1, 2, 3, 6, 9, and 18 while the factors of 35 are 1, 5, 7, and 35. Since the HCF is 1, they are coprime.

## Is 17 and 68 a Coprime number?

17 and 68 are not co-prime because 1 is not the only common factor of these numbers. Example, 17 is another common factor of 17 and 68.

## What is the GCF of 12 and 23?

We found the factors and prime factorization of 12 and 23. The biggest common factor number is the GCF number. So the greatest common factor 12 and 23 is 1.

## What is the HCF of 17 and 51?

The common factors of 17 and 51 are 17, 1, intersecting the two sets above. In the intersection factors of 17 ∩ factors of 51 the greatest element is 17. Therefore, the greatest common factor of 17 and 51 is 17.

## What is the GCF of 17 and 21?

We found the factors and prime factorization of 17 and 21. The biggest common factor number is the GCF number. So the greatest common factor 17 and 21 is 1.

## What is the factor of 17 and 68?

Factors of 17: 1 and 17. Factors of 68: 1, 2, 4, 17, 34, and 68. The greatest factor on the two lists that they have in common is the GCF of 17 and 68. Therefore, the GCF of 17 and 68 is 17.

## What is the HCF of 18 and 48?

We found the factors and prime factorization of 18 and 48. The biggest common factor number is the GCF number. So the greatest common factor 18 and 48 is 6.

## What is the GCF of 19?

Greatest common factor (GCF) of 19 and 28 is 1. We will now calculate the prime factors of 19 and 28, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 19 and 28.

## Is 216 and 215 are Coprime?

Which of the following numbers are co-prime: (a) 18 and 35 (b) 15 and 37 (c) 30 and 415 (d) 17 and 168 (e) 216 and 215 (f) 81 and 16. Answer: … Since both have only one common factor, i.e., 1, therefore, they are co-prime numbers.

## What is Coprime number?

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime if the only positive integer (factor) that divides both of them is 1. Consequently, any prime number that divides one of a or b does not divide the other. This is equivalent to their greatest common divisor (gcd) being 1.

## What is the GCF of 18 and 27?

The factors of 18 are 1, 2, 3, 6, 9, 18. The factors of 27 are 1, 3, 9, 27. The common factors of 18 and 27 are 1, 3 and 9. The greatest common factor of 18 and 27 is 9.
