A composite number is a positive integer greater than 1 that has at least one positive divisor other than 1 and itself. To find a composite number greater than 70, we can look at numbers like 72, 75, 78, and so on. These numbers have factors other than 1 and themselves, making them composite numbers.
For instance, all the even numbers greater than 70 are composite.The next few composite numbers greater than 70 are: 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, ...
Composite numbers less than 70 and greater than 60 are 62, 63, 64, 65, 66, 68 and 69.
