Prime numbers only have one prime factor. The factors of 11 are 1 and 11 but only 11 is considered prime. One is the other factor and it is neither prime nor composite. The only Prime number with a prime factor that totals 11 is 11.
You will get the greatest product if you choose the greatest possible numbers in both cases, i.e., 9 x 99.
Yes - if two numbers share no common factors (besides 1) the least common multiple will be the product of the numbers.
900 - 30 times 30
93 x 862 = 80,166
Product
Their product.

Yes, if they have no common factors other than one.

Product
If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.
The LCM is the product of the two numbers if and only if the two numbers are co-prime. That they are co-prime means they have no factors in common so that their GCF is 1.
Factors multiply. The numbers in the middle of the Venn diagram are common factors. If there are two or more, their product will give you the greatest common factor.
Yes. Composite numbers can be written as the product of prime factors.
20 x 21 = 420
