5 + 23 = 28 11 + 17 = 28
23 + 5
How many numbers are in 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.
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.
None of this works. There aren't two prime numbers that multiply to 75 and the only two that add to it are 73 and 2. There aren't two prime numbers whose difference is 19. Two numbers that satisfy those conditions are 47 and 28, but 28 isn't prime.
11 and 17 are both prime numbers which added together make 28. So are 23 and 5.
5 + 23 = 28 11 + 17 = 28
23 + 5

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.
28 is the product of the prime numbers 2 x 2 x 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.
28 = 2x2x7
17, 19, and 23. All the other numbers have more than two factors.
2 x 2 x 7
Oh, dude, the Highest Common Factor (HCF) of 8 and 28 is like the coolest number that can divide both of them without leaving a remainder. So, for these two numbers, the HCF is 4 because 4 is the largest number that can divide both 8 and 28 evenly. Like, that's math for you, man.
