Factors of xix by Prime Factorization

Prime factorization is a way of expressing a number as a product of its prime factors. The number 19 has a unique factorization because this is the simply way it can be expressed: 19 = one × 19. This is the prime factorization of 19.

Factors of eighteen tin can be establish similarly. Let's run into how:

When we write a number equally a product of its factors, nosotros say that the number has been factorized.

Let's see a few examples of prime factorization.

Prime factorization of 18

Factor Tree of 18

So, the prime factors of 18 are 3 and ii.

We tin can write 18 = 3 × 3 × two

Prime factorization of 20

Factor tree of 20

And then, the prime factors of 20 are two and v.

Nosotros tin can write xx = 2 ×two × 5

Factors of xix in Pairs

Factor pairs of nineteen are the pairs of factors that, when multiplied together, requite the product equal to the number nineteen. Like all other primes greater than 2, xix has no factors apart from one and itself. So, information technology has a unique gene pair, that is, 1 and xix.

Important Notes:

The number xix has merely ii factors, ane and the number itself.
The prime factorization of xix is 19 = i × 19
The number nineteen has only one factor pair.

Factors of nineteen Solved Examples

Example one:Sussane wants to decode the terminal two digits of the Pin of her ATM card. She knows that the number formed by the last 2 digits is a factor of nineteen but not a gene of 36.

Can you decode her Pivot?

Solution:

Since nineteen is a prime, it has just two factors, ane and 19.

The factors of 36 are i, 2, iii, 4, 6, 9, 12, 18, and 36.

We notice that 19 is a factor of 19 simply not a factor of 36.

So, the required 2-digit number is xix.
Example 2:Jacky's teacher gave him a listing of numbers: 23, 19, twenty, 18, and 26. The teacher asked him a few questions every bit shown below. Which is the largest prime number on the list? How many common factors do 20 and 18 have? Which number has the largest prime gene in the list?

Solution:

At that place are but two prime numbers in this list, which are 19 and 23.

23 is a prime because the factors of 23 are i and the number itself.

So, 23 is the largest prime number on the list.

Let'due south calculate the factors of xx and 18.

Factors of 20: 1, 2, four, v, 10, and 20

Factors of 18: 1, 2, 3, six, ix, and 18

So, numbers 20 and xviii accept 2 common factors.

Since 23 is the largest prime in the list, information technology has the largest prime cistron, i.e., 23.
Example 3: Detect the product of all the prime factors of 19.

Solution:

Since the prime factors of 19 are xix. Therefore, the product of prime factors = 19 = 19.

FAQs on Factors of 19

What are the Factors of nineteen?

The factors of 19 are i, 19 and its negative factors are -1, -xix.

What is the Greatest Common Factor of xix and 14?

The factors of xix are 1, xix and the factors of 14 are i, 2, 7, xiv. xix and xiv take only one mutual gene which is i. This implies that nineteen and 14 are co-prime number.

Hence, the Greatest Mutual Cistron (GCF) of 19 and fourteen is ane.

What are the Common Factors of 19 and 17?

Since the factors of 19 are ane, 19, and factors of 17 are 1, 17. Hence, xix and 17 have only ane common gene which is one. Therefore, 19 and 17 are co-prime.

What are the Prime number Factors of xix?

The prime factor of xix is 19.

What is the Sum of the Factors of xix?

Factors of 19 are 1, 19 and, the sum of all these factors is 1 + 19 = twenty
