"Solution: Given find the composite
number between 60 and 70 whose prime factors have a sum of 12
hence the number is 64=2*2*2*2*2*2
2+2+2+2+2+2=12
answer is 64"
What are Composite Numbers
A number which is dividing by positive divisor other than one or itself is called as composite number. A composite number is always positive integer. In other words, If the integer n is greater than zero and the divisors are 1 < a, b < n means the integer ‘n’ is composite number.
