Some multiplication facts for 81 are 9 x 9 3 x 27 1 x 81
-2 x 3
Product of its prime factors are: 3*3*5 = 45
Fact families consist of related addition and subtraction or multiplication and division facts that use the same numbers. Understanding multiplication facts helps you recognize that division is essentially the inverse operation. For example, knowing that (3 \times 4 = 12) allows you to understand that (12 \div 4 = 3) and (12 \div 3 = 4). Thus, mastering multiplication facts equips you to easily and accurately perform division.

The "multiplication facts" may be numbered differently in different textbooks, so it is really hard to guess what multiplication facts you are talking about. Better use the standard names, for example, "commutative property", "associative property", etc. For a multiplication such as 3 x 7, you either memorize the tables, your you do the repeated addition (3 x 7 = 7 + 7 + 7, that is, 7 appears 3 times as an addend.)
As a product of its prime factors: 2*3*3*5 = 90
Fact families illustrate the relationships between addition, subtraction, multiplication, and division. By understanding a multiplication fact, such as 3 x 4 = 12, you can easily derive its corresponding division facts, like 12 ÷ 4 = 3 and 12 ÷ 3 = 4. This interconnected knowledge allows you to solve division problems more efficiently and reinforces your overall understanding of these mathematical operations. By mastering multiplication facts, you can quickly access the necessary division facts within the same fact family.
A fact family is a group of related addition and subtraction or multiplication and division facts that use the same numbers. For the numbers 3, 6, and 18, the multiplication facts are 3 × 6 = 18 and 6 × 3 = 18. The corresponding division facts are 18 ÷ 3 = 6 and 18 ÷ 6 = 3. Together, these facts illustrate the relationships between the numbers in the fact family.
