## What is the HCF of 17 and 23?

We found the factors and prime factorization of 17 and 23.

The biggest common factor number is the GCF number.

So the greatest common factor 17 and 23 is 1..

## How do you find the HCF?

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

## How do you find the HCF of 3 numbers?

To find out HCF of three given numbers using division method, Step 1: Find out HCF of any two numbers. Step 2: Find out the HCF of the third number and the HCF obtained in step 1. Step 3: HCF obtained in step 2 will be the HCF of the three numbers.

## What is the HCF of 16 and 21?

We found the factors and prime factorization of 16 and 21. The biggest common factor number is the GCF number. So the greatest common factor 16 and 21 is 1.

## What is the GCF of 23?

The prime factorization of 23 is: 23. The prime factorization of 29 is: 29. The prime factors and multiplicities 23 and 29 have in common are: 1. 1 is the gcf of 23 and 29.

## What is the LCM of 17 and 5?

Least common multiple (LCM) of 5 and 17 is 85.

## What is the HCF of 15 and 20?

5Greatest common factor (GCF) of 15 and 20 is 5. We will now calculate the prime factors of 15 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 20.

## What is the HCF of 17?

Of two prime numbers is 1 because prime numbers doesn’t any other factor except themselves and 1. So for all primes the HCF is 1. 17 and 19 are primes so the HCF of both the numbers is 1.

## What is the greatest common factor of 29 and 17?

We found the factors and prime factorization of 17 and 29. The biggest common factor number is the GCF number. So the greatest common factor 17 and 29 is 1.

## What is the LCM of 89 and 25?

What is the least common multiple of 89 and 25? – The lcm of 89 and 25 is 2225.

## What is the HCF of 8 and 10?

Greatest common factor (GCF) of 8 and 10 is 2. We will now calculate the prime factors of 8 and 10, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 8 and 10.

## How do you find the least common multiple of a number?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

## What is the HCF of 17 and 5?

The biggest common factor number is the GCF number. So the greatest common factor 5 and 17 is 1.

## What is the HCF of 12?

Find the highest common factor (H.C.F) of 12 and 18. Factors of 12 = 1, 2, 3, 4, 6 and 12. 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 is the HCF of 12 15 and 21?

3H.C.F of 12, 15 and 21 = 3 [HCF(Highest Common Factor) of two or more numbers= Product of the smallest Power of each common prime factor involved in the numbers.]

## What is the GCF of 7/15 and 21?

The common factors for 7,15,21 7 , 15 , 21 are 1 . The GCF (HCF) of the numerical factors 1 is 1 .

## 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.

## What is the greatest common factor of 6 and 18?

Greatest common factor (GCF) of 6 and 18 is 6. We will now calculate the prime factors of 6 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 6 and 18.
