If x is the addition of the prime numbers' between 1 and 6; and y the H.C.F of 6,9,15. Cal. Product of x and y

Answer 1

Prime numbers between 1 and 6 are: 1, 2, 3, 5

Sum of prime numbers = x = 1 + 2 + 3 + 5 = 11

Find the Highest common factor of 6, 9 ,15

Prime factorization of 6 =  2 X 3

Prime factorization of 9 = 3 X 3

Prime factorization of 15 = 3 X 5

GCF = HCF = 3 = y

Product of x and y = 11 * 3 = 33
