There are an infinite number of integers with "only 7 factors". Any number which is the product of exactly 7 prime numbers.

Factors are numbers that multiply together to create a product.

Yes. Composite numbers can be written as the product of prime factors.

30, 42, 66, 70, 78

They are 30, 42, 63, 66, 70 and 78.

If the two numbers have no prime factors in common, their LCM will be their product. If there are prime factors in common, their LCM will be less than their product.

numbers that are multipied together to give a product are called factors
