Answer:
63
Step-by-step explanation:
A composite number is a whole number. It can be defined as a number that is divisible by 1, itself and other factors. This means a composite number has two or more factors. A prime number cannot be a composite number.
The seven smallest composite numbers are:
4, 6, 8, 9, 10, 14, 16,
Their total sum = 4 + 6 + 8 + 9 + 10 + 14 + 16 = 63
Therefore, the sum of the seven smallest composite numbers which cannot be determined to be composite simply by using the divisibility rules (for 2,3,4,5,6,8,9 or 10) is 63.
