The sum of the composite numbers between 1 and 50 is 936.
1, 2, 5, 7, 10, 14, 35, 70

ANSWER: 70 and 80 are not prime numbers. They are composite numbers:70 is a composite number because the factors of 70 other 1 and itself (70) are 2, 5, 7, 10, 14, and 35.80 is also a composite number because the factors of 80 other 1 and itself (80) are 2, 4, 5, 8, 10,16, 20, and 40.

A Composite Number can be divided evenly by numbers other than 1 or itself.The Composite Numbers Between 1 and 10 are as follow.4, 6, 8, 9, 10.
The composite numbers between 1 and 10 are 4, 6, 8, 9, 10. And their sum is 37.
The numbers 4, 6, 8, 9, 10 are composite numbers between 1 and 10 (including 10).
