Prime Numbers

It is: 2*2*5*5 = 100

write the prime factorization of the number.

simple as that.

The prime factorization of 525 is:

525=3×5

2

×7

Step-by-step:

525÷5=105

105÷5=21

21=3×7

So:

525=5×5×3×7

or written with exponents:

3×5

2

×7

The prime numbers between 30 and 50 are 31, 37, 41, 43, and 47. These numbers are only divisible by 1 and themselves, fulfilling the definition of prime numbers.

15 is. In addition to ' 1 ' and itself, it has the additional factors 3 and 5 .

The number 4567 278 is easy to identify as a composite number because it is even, ending in 8. All even numbers greater than 2 are divisible by 2, indicating they have at least three factors: 1, 2, and the number itself. Therefore, it cannot be a prime number, which is defined as having exactly two distinct positive divisors.

Except for '2' , there are no even prime numbers.

Even numbers end in 0,2,4,6,8

Except for '2' , Prime numbers are all odd numbers. However, NOT all odd numbers are Prime Numbers.

All odd numbers end in 1,3,5,7,9.

e.g. 13 is a prime number.

15 is NOT a prime number. It is composite ( 3 x 5 = 15)

Hence any number ending in '6' is EVEN and NOT a prime. e.g. 36.

To express 90 as a product of its prime factors in ascending order, we first find its prime factorization. The prime factors of 90 are 2, 3, and 5. Therefore, 90 can be expressed as ( 2^1 \times 3^2 \times 5^1 ). In ascending order, the prime factorization is ( 2 \times 3^2 \times 5 ).

Yes, if the product of two numbers is even, at least one of the numbers must be even. However, both numbers can be even as well, in which case their product will also be even. For example, if both numbers are 2 and 4, their product (8) is even. Thus, while both can be even, it is not a requirement; only one needs to be even for the product to be even.

'27' is NOT a prime number.

It is a composite of 3 x 9 = 27

Composite because it will divide by '3'

Hence

3)159 = 53

So 159 is composed ( multiple) of 3 x 53 = 159

NB '3' & '53' are both Prime Numbers.

Let the number be n-1, n , n+1 ( consecutive).

Adding

n - 1 + n + n + 1 = 504

3n = 504

n = 504/3

n = 168

n-1 = 167

n + 1 = 169

Hence the consecutive njumberscare ; - 167, 168, 169

It is prime

By the very fact that it ends in an even number , '6', ,then it is divisible by '2' . Hence it is a compound number.

NB . Other than '2' , there are no other even prime numbers.

All prime numbers are 'odd' numbers.

NNB

EVen numbers end in 0,2,4,6,8

Odd Numbers end in 1,3,5,7,9.

NNNB Not all odd numbers are prime numbers. e.g. 33 = 3 x 11

Yes, Prim Everdeen dies in "The Hunger Games" series. Her death occurs in the final book, "Mockingjay," during a bombing in the Capitol, which is orchestrated by the enemy forces. Katniss Everdeen, her sister, is devastated by her loss, as Prim had been a symbol of hope and innocence throughout the series. This event plays a crucial role in shaping Katniss's actions and decisions in the story's conclusion.

No, 12 and 16 are not relatively prime because they share a common factor greater than 1. Both numbers can be divided by 4, making their greatest common divisor (GCD) equal to 4. Since they have a GCD greater than 1, they are not relatively prime.

NO!!! THey are composite numbers.

However, they are the products of prime numbers.

27 = 3 x 3 x 3 & '3' is a prime number.

70 = 7 X 5 x 2 & '7' , '5' & '2' are prime numbers.

The five prime numbers that multiply together to equal 420 are 2, 2, 3, 5, and 7. This can be expressed as (2^2 \times 3 \times 5 \times 7 = 420). Note that while 2 is repeated, all other numbers listed are distinct prime numbers.

Composite!!!!

However, as composite number they can be formed from prime numbers.

e.g. 5 is a prime number.

5^(2) ( five squared) = 5 x 5 = 25 is composite, because you have multiplied '5' by itself.

Prime factorization is the process of expressing a number as a product of its prime factors. For example, the prime factorization of 28 is (2^2 \times 7), which means that 28 can be divided by the prime number 2 two times and by the prime number 7 once. This representation uniquely identifies the number and is useful in various mathematical applications, such as finding the greatest common divisor or least common multiple.

The only two prime numbers for which this can be the case are 2 and 5 - since one of the prime numbers has to be even.

I assume you are asking the question "what two prime numbers sum to 44".

There may be other pairs of prime numbers that sum to 44, but 37 and 7 are both primes and their sum = 44.
