What is a product of a prime number?

Writing a Product of Prime Factors 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, we can write the number 72 as a product of prime factors: 72 = 2 3 ⋅ 3 2 . The expression 2 3 ⋅ 3 2 is said to be the prime factorization of 72.

What is the prime factorization 162?

Factors of 162 By Prime Factorization Therefore, Factors of 162 are 2 × 3 × 3 × 3. Now that we have done the prime factorization of 162, we can multiply them and get the other factors.

How do you write 108 as a product of its prime factors?

In index form: 108 = 2^2 × 3^3.

What is 135 as a product of prime factors?

The prime factorization of 135 is 3 × 3 × 3 × 5.

What is 72 as a product of prime factors?

For example, we can write the number 72 as a product of prime factors: 72 = 2 3 ⋅ 3 2 . The expression 2 3 ⋅ 3 2 is said to be the prime factorization of 72.

What is 63 as a product of its prime factors?

Since, the prime factors of 63 are 3, 7. Therefore, the product of prime factors = 3 × 7 = 21.

How do you write product of prime numbers?

To write any number as a product of its prime factors, we should find all those prime numbers which when multiplied together form the number. Hence, we should divide the given number consistently by prime numbers starting with 2, which is first prime number and continue till all factors are prime numbers.

What does ‘product of prime numbers’ mean?

“…product of prime numbers” means that we multiply prime numbers together. So, by multiplying prime numbers we can create any other whole number.

What is the product of the first ten prime numbers?

The product of the first ten prime numbers must be divisible by: Thanks in advance. well the first 10 prime numbers are 2,3,5,7,11,13,17,19,23,29. The product of two of the primes, 2 and 11 is 22. Therefore the product of the first ten primes which contains 2 and 11 will be 22.

What is 42 as product of prime factors?

The only way to write 42 as the product of primes (except to change the order of the factors) is 2 × 3 × 7. We call 2 × 3 × 7 the prime factorization of 42.
