This video breaks down what happens when a number is divisible by another number and introduces the concept of co-primes. We'll start by exploring factors and divisibility through clear examples with 24 and 36, then discover an important pattern: **if A is divisible by B, then A is divisible by all factors of B**. Next, we'll introduce co-primes and learn when two numbers can be multiplied together to determine divisibility. You'll see this rule in action through concrete examples like 80 (divisible by 4 and 5) and 60 (divisible by 3 and 5). We'll also cover the critical warning: this rule only works when the numbers are co-primes! Learn why 12, 4, and 6 break the pattern and understand the mathematical reasoning behind each rule.
