43, 23 and 2
The three numbers will have a mean of 204/3 = 68. The two numbers are therefore 66, 68, 70.
52, and 68
23
The two numbers are 43 and 68. 43 + 68 = 111, while 68 - 43 = 25
HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .
The sum of the prime numbers 2, 5, and 61 is 68.
68
There are no such whole numbers. The sum of three consecutive whole numbers must be a multiple of 3; as 68 is not a multiple of 3 (68 = 3 × 22 2/3) it cannot be the sum of three whole numbers.
31 is the only prime number between 30 and 40
The three numbers will have a mean of 204/3 = 68. The two numbers are therefore 66, 68, 70.
66 + 67 + 68
52, and 68
How about: 2*2*17 = 68 as a product of its prime factors
17 is a prime number but 68 is Composite.
No, it is composite.
23
The numbers 71, 73 and 79 are prime.
