28 = 2x2x7
Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
No, because 28 can only be calculated as a product in the following ways: 1 x 28 2 x 14 4 x 7 In the above cases, 28, 14 and 4 are all non-prime numbers, which means that 28 cannot be a product of 2 prime numbers alone.
Prime factorizations are unique. No other number will have exactly the same number of prime factors as 28. Multiples of 14 will have some of the same factors.
The numbers are 13 and 41. And you do not need to know that they are prime in order to find the answer. The sum (54) and difference (28) provide all the necessary information.
28 = 2x2x7
23 is the only prime number between 20 and 28.
Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
The prime numbers (factors) of 28 are: 2 and 7
No, because 28 can only be calculated as a product in the following ways: 1 x 28 2 x 14 4 x 7 In the above cases, 28, 14 and 4 are all non-prime numbers, which means that 28 cannot be a product of 2 prime numbers alone.
A prime number is a number that is not evenly divisible by any number except itself and one; it cannot be factored any lower. However, four is the product of two and two to begin with, and when you create multiples of four, you give it more factors (22, 24, 26, 28, etc.).
Prime factorizations are unique. No other number will have exactly the same number of prime factors as 28. Multiples of 14 will have some of the same factors.
The numbers are 13 and 41. And you do not need to know that they are prime in order to find the answer. The sum (54) and difference (28) provide all the necessary information.
29
Oh honey, let me break it down for you. The prime numbers between 18 and 28 are 19 and 23. Don't waste your time looking for any others in that range, those two are the cream of the crop. Math doesn't have to be complicated, just like a good slice of pie - simple and satisfying.
28 is not a prime number because it is divisible by 2, 4, 7, and 14. Prime numbers are only divisible by 1 and themselves without any other factors.
