It is 70 or 42 that have exactly 3 prime factors
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.
The prime numbers between 13 and 28 are 13 17 19 23 Multiples of 7 in that range include 14, 21 and 28.
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.
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.
28 = 2 x 14 and so on 23 is prime 33 = 3 x 11 47 is prime
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.
28 is a composite number as it is divisible by numbers other than itself and one. 28 is divisible by 1, 2, 4, 7, 14 and 28
The prime numbers between 13 and 28 are 13 17 19 23 Multiples of 7 in that range include 14, 21 and 28.
They are: 1 2 4 7 14 and 28 note that 2 and 7 are prime numbers
2 x 14 4 x 7
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.
14 can never be the least common factor of two numbers. The least common factor of any two numbers is 1.
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.
28 = 2 x 14 and so on 23 is prime 33 = 3 x 11 47 is prime
1, 2, 4, 7, 8, 14, 28, 56 2 and 7 are prime.
