Factors of 19 by Prime Factorization

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

Factors of 18 can be establish similarly. Let's encounter how:

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

Allow's encounter a few examples of prime factorization.

Prime factorization of 18

Factor Tree of 18

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

We tin can write 18 = 3 × 3 × 2

Prime factorization of twenty

Factor tree of 20

So, the prime factors of twenty are 2 and 5.

We can write xx = ii ×2 × 5

Factors of nineteen in Pairs

Cistron pairs of 19 are the pairs of factors that, when multiplied together, requite the product equal to the number 19. Like all other primes greater than 2, 19 has no factors apart from one and itself. So, information technology has a unique factor pair, that is, 1 and 19.

Important Notes:

The number xix has only two factors, 1 and the number itself.
The prime number factorization of xix is 19 = ane × 19
The number xix has simply one factor pair.

Factors of 19 Solved Examples

Example 1:Sussane wants to decode the terminal two digits of the PIN of her ATM menu. She knows that the number formed by the last two digits is a factor of 19 simply not a factor of 36.

Can you decode her Pivot?

Solution:

Since 19 is a prime number, it has merely two factors, 1 and 19.

The factors of 36 are 1, 2, iii, four, 6, 9, 12, 18, and 36.

Nosotros discover that 19 is a cistron of xix only non a gene of 36.

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

Solution:

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

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

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

Allow's calculate the factors of 20 and eighteen.

Factors of 20: 1, 2, 4, 5, x, and 20

Factors of xviii: 1, ii, 3, half dozen, nine, and 18

So, numbers 20 and 18 have 2 common factors.

Since 23 is the largest prime number in the list, it has the largest prime gene, i.e., 23.
Example 3: Find the product of all the prime factors of nineteen.

Solution:

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