## 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 prime factorization of 11?

The prime factorization of 11 is 1 × 11. The number 11 is a prime number, because its only factors are 1 and itself.

## What is the prime factorization of 13?

Since 13 can only be divided evenly by 1 and 13 (itself), it is called a prime number. A prime number can only be divided evenly by one and itself. The other numbers such as 6, 12, and 21 are called composite numbers since they can have many factors (more than two).

## 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 LCM of 7429?

Least common multiple (LCM) of 7429 and 7436 is 55242044.

## What is the HCF of 15 and 18?

The common factors of 15 and 18 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 18 the greatest element is 3. Therefore, the greatest common factor of 15 and 18 is 3.

## What is the HCF of 4 and 15?

4 = 2 × 2 and 15 = 3 × 5; Since there is no common prime factor, so HCF of 4 and 15 is 1.

## What is the biggest common factor of 12 18 and 30?

The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set of numbers 18, 30 and 42 the GCF = 6.

## What is the prime factorization of 9999?

101 is one of the factors! The orange divisor(s) above are the prime factors of the number 9,999. If we put all of it together we have the factors 3 x 3 x 11 x 101 = 9,999. It can also be written in exponential form as 32 x 111 x 1011.

## Can you write prime factorization of a prime number?

A prime number can only be divided by 1 or itself, so it cannot be factored any further! Every other whole number can be broken down into prime number factors. … This idea can be very useful when working with big numbers, such as in Cryptography.

## How do you find the prime factorization of an integer?

Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.

## What is the LCM of 26 and 91?

Answer: The HCF of 26 and 91 is 13. The LCM of 26 and 91 is 182.

## How do you find the largest prime number?

50th Known Mersenne Prime Found! The prime number is calculated by multiplying together 77,232,917 twos, and then subtracting one. It weighs in at 23,249,425 digits, becoming the largest prime number known to mankind. It bests the previous record prime, also discovered by GIMPS, by 910,807 digits.

## What is the prime factorization of 16?

16 = 1 x 16, 2 x 8, or 4 x 4. Factors of 16: 1, 2, 4, 8, 16. Prime factorization: 16 = 2 x 2 x 2 x 2, which can also be written 16 = 2⁴.

## What is a prime factorization of 20?

20 is a composite number. 20 = 1 x 20, 2 x 10, or 4 x 5. Factors of 20: 1, 2, 4, 5, 10, 20. Prime factorization: 20 = 2 x 2 x 5, which can also be written 20 = 2² x 5.

## What is the prime factorization of 28?

28 is a composite number. 28 = 1 x 28, 2 x 14, or 4 x 7. Factors of 28: 1, 2, 4, 7, 14, 28. Prime factorization: 28 = 2 x 2 x 7, which can also be written 28 = 2² x 7.

## What is the factor of 7429?

23 is one of the factors! The orange divisor(s) above are the prime factors of the number 7,429. If we put all of it together we have the factors 17 x 19 x 23 = 7,429. It can also be written in exponential form as 171 x 191 x 231.

## What is prime factorization method?

The method of prime factorization is used to “break down” or express a given number as a product of prime numbers. More so, if a prime number occurs more than once in the factorization, it is usually expressed in exponential form to make it look more compact.
