4x2,8x1,
5 and 3 are two prime numbers which on adding give 8.
They are: 5+3 = 8
The prime numbers less than 100 that contain an 8 are 83 and 89. So, there are two prime numbers that are less than 100 and contain an 8.
No. Not even close. Examples: 4+4=8 8+8=16 16+16=32 . . .4, 8, and 16 are not prime numbers.
Two numbers: 5 and 7 :)
2 and 17
3 and 5
Numbers that have 2 factors are prime numbers; Numbers that have 4 factors are either: * the cube of a prime; or * the product of two different primes; Numbers that have 8 factors are either: * a prime to the power 7; * the product of a prime cubed and different prime; * the product of three different primes.
The only prime factor of 8 is 2. You need at least two numbers to have a difference.
When the two numbers are coprime. Coprime numbers need not be prime numbers - they must not have any factor in common (other than 1). So, for eaxmple, neither 8 nor 9 are prime numbers but they are coprime and so, LCM(8 , 9) = 72
There are eight prime numbers under 20.
17 is a prime number. 8 and 12 are not prime numbers.
