## What are the prime factors of 28?

2 Answers.

The prime factorization of 28 is 22⋅7 ..

## What is the difference between factor and prime factor?

Factors are numbers that can be multiplied together to make another number. … Prime numbers are numbers that have exactly two factors, 1 and itself (i.e. 2, 3, 5, 7, 11,….). So, prime factorization is writing the prime numbers that will multiply together to make a new number as a multiplication problem.

## What are the prime factors of 64?

So, the prime factors of 64 are written as 2 x 2 × 2 x 2 x 2 x 2 or 26, where 2 is a prime number.

## What are the prime factors of 84?

So, the prime factorisation of 84 is 2 × 2 × 3 × 7 or 22 × 3 × 7, where 2, 3 and 7 are the prime numbers.

## What are the prime factors of 36?

When a composite number is written as a product of all of its prime factors, we have the prime factorization of the number. For example, the number 36 can be written as a product of primes as: 36 = 2² x 3². The expression 2² x 3² is said to be the prime factorization of 36.

## How many prime numbers are there in 36?

four prime factorsSo 36 has four prime factors: 2, 2, 3, & 3. The factors of 36 are: 1,2,3,4,6,9,18,and 36. But if you want only prime factors they are 1,2,and 3. Prime factorization is representing a number in the multiples of prime factors.

## What is prime factor?

more … A factor that is a prime number. In other words: any of the prime numbers that can be multiplied to give the original number. Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers).

## What are the common factors of 28 and 36?

The greatest common factor circled is the GCF. The GCF of 28 and 36 is 4. Step 1: Write the prime factorization of both numbers. Circle the factors common to both.

## What is a prime factor of 24?

Answer and Explanation: The prime factorization of the number 24 is 2 × 2 × 2 × 3.

## What are the prime factors of 77?

The prime factorization of 77 is 7 × 11.

## What are all the factors of 36?

## Is 36 a perfect number?

-perfect numbers are 36, 1800, 2700, 17424, … (OEIS A054980).

## What two numbers make 36?

Explanation:1×36=36.2×18=36.3×12=36.4×9=36.6×6=36.

## What is the greatest factor of 36?

1, 2, 3, 4, 6, 9, 12, 18, and 36. 1, 2, 3, 6, 9, 18, 27, and 54. Although the numbers in bold are all common factors of both 36 and 54, 18 is the greatest common factor. The second method to find the greatest common factor is to list the prime factors, then multiply the common prime factors.

## What are the prime factors of 91?

Factors of 91: 1, 7, 13, 91. Prime factorization: 91 = 7 x 13.

## What are the prime factors of 63?

So, the prime factorisation of 63 is 3 × 3 × 7 or 32 × 7, where 3 and 7 are the prime numbers.

## Why is 36 not a prime number?

For 36, the answer is: No, 36 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 36) is as follows: 1, 2, 3, 4, 6, 9, 12, 18, 36. For 36 to be a prime number, it would have been required that 36 has only two divisors, i.e., itself and 1.

## What are the prime numbers to 100?
